First day at @NASA @NASAJPL

At @Keysight, we take quantum seriously. Our @Riscure is working on PQC validation and hardware-security testing to prepare for the post-quantum era. In parallel, our @KeysightQ team supports customers in developing quantum key distribution (QKD) hardware solutions.

In the classical era, static coins were considered a stabilizing factor for Bitcoin’s scarcity. In the quantum era, they could turn into vulnerabilities. That’s why thinking about security ahead of time matters, once the quantum era begins, it’s late to patch the past.

When I go to public talks, I get asked the same question: “What happens to 🪙𝐁𝐢𝐭𝐜𝐨𝐢𝐧 when ⚛️𝐐𝐮𝐚𝐧𝐭𝐮𝐦 𝐂𝐨𝐦𝐩𝐮𝐭𝐞𝐫𝐬 arrive?” The Federal Reserve Board just published a paper in last week addressing that. federalreserve.gov/econres/feds/h…

@Travis_Sch Yes, if you go down, you will see the 1,000‑qubit dilution fridge there. 😊

What does this thing sit on top of? Asking given the ladder in the picture....

Today, @Keysight announced the delivery of a 1,000‑qubit control system – 𝐓𝐡𝐞 𝐰𝐨𝐫𝐥𝐝’𝐬 𝐥𝐚𝐫𝐠𝐞𝐬𝐭 𝐜𝐨𝐦𝐦𝐞𝐫𝐜𝐢𝐚𝐥 𝐪𝐮𝐚𝐧𝐭𝐮𝐦 𝐜𝐨𝐧𝐭𝐫𝐨𝐥 𝐩𝐥𝐚𝐭𝐟𝐨𝐫𝐦.

Korean government just announced that quantum computers will be used to train League of Legends strategy. Not joking.

🎊 Proud to be part of a team at @Keysight . We are honored to provide solution to the newly developed 256-qubit quantum computer at the @riken_en-@Fujitsu_Global in Japan. shorturl.at/ZIpJD

Happy #WorldQuantumDay --- for a cute surprise, check out the home page of google.com today! #quantum #GoogleDoodle #Noogler

Are you curious how to control the transition frequency of your superconducting qubit accurately using magnetic flux? This is useful in many experiments performed with superconducting circuits, e.g. in quantum computation, or when using qubits as sensors for electromagnetic radiation. In the new manuscript "Calibrating Magnetic Flux Control in Superconducting Circuits by Compensating Distortions on Time Scales from Nanoseconds up to Tens of Microseconds" we document the methods which we use in our @qudev Lab (@ETHQuantumCntr, @ETH_physics) and at the @ETH_en Zürich - @psich_en Paul Scherrer Institut #Quantum Computing Hub. Read the @arxiv abstract here arxiv.org/abs/2503.04610 or directly download the manuscript here arxiv.org/pdf/2503.04610. The work was done by Christoph Hellings, @NathanLacroix, @AntsRemm, Richard Boell, Johannes Herrmann, Stefania Lazar, @SebKrinner, @FrancoisSwiadek, Christian Kraglund Andersen, @eichler__chris, @AndreasAtETH and supported by @IARPAnews , the @snsf_ch, and the @ETHFoundation1 .

I am pleased to announce that an early-access preview of the upgraded IBM Quantum Platform is now available. The upgraded introduces several critical new capabilities (see ibm.com/quantum/blog/i…)

At Microsoft Quantum we are racing to build the first utility-scale quantum computer based on topological qubits (darpa.mil/news/2025/quan…). We are also working very closely with our partners to bring their quantum computer technology to life sooner in the Microsoft Quantum platform. I’m hiring people who want to accelerate the timeline to a useful quantum computer, no matter the technology. And I’m excited to post the first positions below. Please consider applying. We will eventually be hiring across the stack (qubits - both theory and experiment, quantum plane architecture, control and readout, hardware integration and component development, and software), so even if you don’t see yourself explicitly in the descriptions below, get in touch. This is your opportunity to be part of a team that’s cutting the line to the first useful quantum computer. We have an amazing team of people at Microsoft Quantum. Join us. Principal Quantum Technical Program Manager: jobs.careers.microsoft.com/global/en/job/… Principal Quantum Hardware Engineer: jobs.careers.microsoft.com/global/en/job/… Senior Quantum Hardware Engineer: jobs.careers.microsoft.com/global/en/job/… And thanks for sharing this post! #QuantumComputing #MicrosoftQuantum #BeanTeam

@saesunkim At this time, there are no planned changes to the #APSSummit25 schedule. We are keeping a close eye on the situation in and around Anaheim, along with nearby airports, and will provide updates as needed.

@APSphysics Thanks!

@APSphysics Are you still planning to host the APS March Meeting in LA? Would love to get an update!
