Happy @UN International Year of Quantum Science & Technology! #IYQ2025

PQ-NEXT Lexicon📓 After we learn about the Physical Qubit, today,we will explore the Logical Qubit A logical qubit is a fault-tolerant unit of quantum information that encodes the state of a qubit across multiple entangled physical qubits using quantum error correction techniques

Comment from @skdh about the recent Majorana 2 quantum chip

We’re proud to share our latest advance in fault-tolerant quantum computing using high-rate quantum low-density parity-check (qLDPC) codes, which we have found directly reduce qubit overhead. With our trapped-ion hardware, we can demonstrate logical qubits with a high encoding rate on a single device, which requires much lower qubit overhead than other popular approaches like the surface code. This result represents substantial progress toward IonQ’s large-scale quantum architecture. Congratulations to the team who have been working across labs on this research: Edwin Tham, Michael Goldman, Shantanu Debnath, Ashay Patel, Jyothi Saraladevi, Jason Nguyen, Erik Nielsen, Neal Pisenti, Kenneth Wright, John Gamble, and Nicolas Delfosse.

Check out our recent achievement of #PracticalQuantumAdvantage in this recent @LesEchos feature. By augmenting an IBM quantum computer with our performance-management software, we delivered a 3,000 times algorithmic speedup for materials discovery. buff.ly/wma8nMq

Quantum computing advances when more people can build, experiment, and discover.​ With PsiQuantum Construct now open-access, researchers and developers have free tools to design and explore quantum algorithms.​ We’re excited to see what you build: bit.ly/4o40RPK

Today, Quantinuum officially begins trading on NASDAQ under the ticker symbol QNT. Today’s milestone is the direct result of the dedication of our team, trust of our partners, and support of the entire quantum community. Thanks to everyone who helped us reach this historic day.

The EU is making it easier than ever to ditch the car keys and hop on your bike. The upcoming World Bicycle Day on Wednesday is the perfect occasion to do so. With our European Declaration on Cycling, we are committed to boosting this experience for you:

40 years since the EU flag was raised in front of our headquarters in Brussels for the very first time. Twelve stars. A single market. Four decades of standing together for unity, solidarity, and diversity. The symbol that fosters Europeans’ sense of community. 🇪🇺

A group of physicists say they've proved that quantum mechanics can be explained without quantum mechanics. I asked ChatGPT, Grok, and Claude what they think about the paper.

The Gaussian integral is a key concept in mathematics, often used in probability, statistics, and physics. It calculates the area under the bell-shaped curve of the Gaussian (or normal) distribution. 📹math.animations

We've started sending invitations for a free, online intermediate-level workshop on quantum computing and programming - QNickel26, focusing on oracular quantum algorithms. It will be held on May 25-29, 18:00-22:00 CEST each day. Details: qaif.org/events/workshops/qn…
