Thank you very much, Niccolo. It really has been an amazing year for IonQ. I'm extremely pleased that 2025 has been such a transformative and record-setting year for us from virtually every lens that I can see from record-setting financial results to exceptionally strong commercial sales globally to unmatched technology breakthroughs like the four 9 fidelity you mentioned. It was the year in which we transformed the company from a single product quantum computing company in 2024 to a full stack quantum platform company, able to deliver not just quantum computing, but as you said, quantum networking, quantum security, quantum sensing, interconnects, laser-based communications, the world's most precise PNT and on and on. In short, from one amazing product to the world's most comprehensive quantum product portfolio. In the process, we also became the Quantum industry's merchant supplier. Yes, as Niccolo noted, we provide components to our pre-group companies in the quantum space. And as you heard from Niccolo, we're not stopping there. We've announced our intent to acquire SkyWater Technologies, already recognized as the most secure fab in the United States. With SkyWater, once it receives regulatory approval, we would have both surety of supply and security in our solutions. With more than $3 billion of cash among our financial firepower, we intend to bring that surety and security in the most advanced and secure products to our customers around the world. Let me highlight our financial results, which help really punctuate what you and I just talked about. IonQ ended 2025 with an exceptional fourth quarter following a record-setting third quarter. Fourth quarter revenues were $61.9 million, even exceeding our own expectations and growing 429% year-over-year. This brought our full year 2025 revenues to $130 million, comprising 202% year-on-year growth. These historically high results mean that IonQ has outperformed our revenue guidance once again, exceeding the midpoint by 55% for the fourth quarter and 20% for the full year. Our full year revenues now exceed the Street expectations for 2025 revenues while the other pure-play quantum players combined. Let me take a moment to talk about some key drivers of what the performance we saw this quarter and this year. First, we saw tremendous demand from customers for our latest fifth-generation 100-qubit tempo system. In fourth quarter, we welcomed KISTI of South Korea as a new customer of our fifth-generation system. This sale highlights IonQ's distinct value and the ability for us to win even against competitors that may be larger than us or more entrenched or bigger marketing dollars. The value and the strength of our products clearly shine through. Customers are choosing to partner with IonQ because of our industry-leading tech road map today and the tech road map we have announced for the next 5 years as well. We also welcomed another new customer, CCRM, one of the world's leading advanced therapeutics accelerators, which plans to use IonQ's Tempo cloud-based solution to do bioprocess optimization, disease modeling and the design and manufacturing of advanced therapies for many health conditions. Yet another commercial success story is with QuantumBasel, which demonstrates our land-and-expand strategy, but also that we treat our customers as partners in a journey, combining theirs with ours. QuantumBasel, who already owns our prior fourth-generation Forte quantum computer, agreed in the fourth quarter to purchase our fifth-generation tempo computer and also obtained access to our future sixth-generation computer, which is still in development, and this is a 256-qubit semiconductor-based computing device we expect to deliver in 2027. This multiyear relationship now -- is now expected to span 7 years from the years we've been with them in the past and the 4 years that Niccolo mentioned with this new arrangement we have with them. It also demonstrates how one compute device can lead to the adoption of an entire road map. QuantumBasel is a testament to how customer relationships turn into enduring partnerships. Beyond computing, we are seeing similar demand and adoption for our networking and post-quantum cybersecurity solutions. As you also heard from Niccolo, we saw quantum networking adoption in Geneva, in Slovakia. And in Romania, IonQ is deploying one of the largest and most complex operationally post-quantum cybersecurity networks in Europe. These national partnerships represent significantly larger networks than in the past and are indicative of the growing adoption of our quantum networking and our quantum security solutions. Turning now to the mix of revenues we saw. For the full year 2025, over 60% of revenue came from commercial customers, marking strong sales in the commercial sector and reflecting the customers, some of whom I named before. And anecdotally, our international sales comprised more than 30% of revenue for the first time, reflecting how our Quantum platform solutions are now resonating worldwide. Because of the breadth of quantum products we are now delivering, our customers' list includes Singtel, SK Broadband, Solace, CERN, IIT, it's a very long list. Importantly, this broadening customer base presents us with a golden opportunity to cross-sell more things to more customers. As we move ahead, we continue focusing on new customer opportunities around the world, including in places like Australia, Italy, Greece, India, Japan, Vietnam, Argentina and many others. Our new CRO and the sales team are taking a very methodical approach to identifying the most compelling opportunities and taking a disciplined pursuit and capture approach. Importantly, our 2025 results included nearly 80% year-on-year organic growth, and I expect this to be even healthier in 2026. We are very pleased to see solid organic growth, of course, even as we have broadened our product portfolio with our Quantum platform. With my second successive quarter now in this role, we are continuing our focus on building strong backlog plus developing a very targeted view of our pipeline in order to make sure that we continuously strengthen our visibility for our financial planning and also that we match demand and supply. As a demonstration of this focus, in our 2025 10-K being filed today, we disclosed that our remaining performance obligations, or RPO, which provides one metric to gauge visibility over several quarters, stood at $370 million at the end of 2025 compared to just $77 million at the end of 2024, which is almost a fivefold increase. Turning now to EBITDA. We reported an adjusted EBITDA of negative $67.4 million for the quarter and negative $186.8 million for the year. I wanted to note that even this adjusted EBITDA is better than the full year adjusted EBITDA guidance that we had provided at the time of our third quarter earnings call. The adjusted EBITDA reflects the fact that we are making investments. We are investing in our business and our key investment area, as you'd expect, continues to be R&D. R&D comprised $96.1 million in Q4. And for the year, it was $305.7 million. That's 123% annual increase. We will continue to invest in R&D as this helps maintain the technological advantage that we deliver for our customers and also creates new IP to extend the value for our customers in the future. We are doubling down on investments in our computing platform, which is already leading the market by multiple years by both investing in our fifth-generation tempo deployments, which are in progress this year, which are already beginning really the build-out of our sixth-generation 256-qubit computing platform, as Niccolo mentioned. And then we have our sights on our seventh-generation system beyond that. Unlike other market players, we are also investing in building our own quantum application, in many cases, in partnership with our customers and also on our own. We are focusing on applications with the highest potential impact with the intent to build once and sell many times. Just a few examples of high-impact applications we might build include quantum high-frequency trading, energy grid optimization, life sciences acceleration and even the design of semiconductor chips in a more effective way. There are many others. To sum it up, our investments in R&D are not just lab experiments. We are bringing Quantum to life and delivering to our customers today. Turning to net income. For the fourth quarter, we reported a positive $753.7 million of GAAP net income, which was mainly due to an approximately $950 million mark-to-market valuation of warrants as required by accounting conventions. Needless to say, the mark-to-market impact warrants are noncash items and valuations are more related to our stock price at any given point and do not represent the operating fundamentals of our business. For the full year 2025, we reported a negative $510 million GAAP net income, which included warrants valuation impact of $66.7 million. Cash, cash equivalents and investments as of December 31, 2025, were $3.3 billion. The strength of our balance sheet provides us with what we consider unprecedented financial firepower to continue to invest in R&D to build out even more new products to invest in go-to-market resources and yes, to also acquire for critical new capabilities or to accelerate our road maps. IonQ is uniquely positioned with the resources, talent and differentiation so we can focus on cementing our market leadership and delivering the world's most advanced quantum technologies in every sector. As for operational excellence, which is so critical for establishing the foundation of future success. This will be one of the top priorities for Niccolo and the leadership team in 2026. And as you said, and as we reported last quarter, we've already turned our focus to this very important area to prepare for the future. Deploying organizational clarity and accountability is one essential ingredient. Manufacturing under a clear leadership, customer deployment under a single leader, sales under a single leader, supply chain under a single leader and applications development ownership. All of these things comprise the building blocks of what you need to be able to ensure that there's accountability and planning. Last quarter, we mentioned we have established a dedicated M&A integrations team. And I'm very pleased to report that since then, we have successfully integrated key functions like HR and finance and are making strong progress on IT consolidation under our new CIO. In short, we have moved to rapidly integrate our acquisitions, increase our execution velocity and deliver on key priorities. I'm pleased to report that our IT cybersecurity teams are now unified under the leadership of our new CIO that Niccolo mentioned, Katie Arrington, who recently joined the team from the Department of War and our CISO, who also brings years of experience with many agencies and also other companies, including through other agencies and reports to Katie. Our goal is to create our products in as highly secure posture as possible. Last quarter, we also spoke about IonQ's unique ability to now leverage the established semiconductor manufacturing process for our next-generation compute. In January of 2026, as Niccolo noted, we announced our intent to acquire SkyWater in order to strengthen our supply chain all the way through to manufacturing. On the close of that transaction, which, of course, must go through a regulatory process, we would acquire SkyWater's trusted fab U.S.-based Tier 1 foundry, enabling us to ensure we would have the availability, security and quality to scale our chip-based road map, bringing us both CMOS as well as advanced packaging capability. This acquisition also builds on our already existing merchant supplier business model in which we currently serve other quantum players today. As the pacesetter of the quantum industry, we do see it as a key responsibility to also help ensure in the overall development of our ecosystem. Let me turn now to fiscal year 2026 guidance. On the shoulders of the amazing 2025 numbers that we saw, we feel we have built a strong foundation for yet another year of strength in 2026. With that in mind, we are pleased to offer the following financial guidance for full year 2026 as well as for the first quarter. For 2026, we are projecting revenues of between $225 million to $245 million for full year and $48 million to $51 million for the first quarter. Our projected revenue growth is anchored by a continued expansion of our customer base, both in terms of number of customers, number of offerings that we bring to the market. And as I mentioned earlier, our guidance today is based on visibility stemming from a healthy backlog and an attractive pipeline that we will work methodically to convert. We are projecting adjusted EBITDA to be between negative $310 million and negative $330 million for the full year 2026. And as I discussed today, this range represents our continued investment in critical R&D to help drive the next generation of Quantum solutions across our portfolio. It goes without saying that since we announced SkyWater transaction has not closed, our guidance metrics do not reflect SkyWater. We continue to operate as separate publicly traded companies until such time as approvals are in hand. As Niccolo mentioned at the beginning of his comments, IonQ has rapidly established itself with the world's most unique set of products and capabilities, and we are for sure not stopping there. Compared to any other quantum pure-play one might look at, our product suite is unmatched. Our talent density is exceptional. Our business is global. We are actively selling into commercial deployments, not just labs. And critically for the future of Quantum, we possess a merchant supplier business model that enables the entire Quantum ecosystem to develop and succeed over time as we progress. And yes, while we do now and then take a moment to celebrate our progress like today, and I must say it does feel good. Tomorrow, the entire IonQ team will get up and continue to dash towards delivering the world's most advanced, innovative and complete quantum solutions for our customers. With that, operator, can you please open the call for Q&A?
