CERN Demonstrates Coherent Control of Antiproton Spin State — an Antiqubit
BASE, which is a CERN initiative to compare the properties of protons and antiprotons, has announced results wherein an antiproton was kept in a coherent oscillation between spin states for 50 seconds. The linked news release describes this as the first antimatter qubit. That’s quite a mouthful, but as a former physicist myself, I’m a […]
Phasecraft Announces Improved Quantum Algorithm
Quantum computing is drawing nearer and nearer to real practical applications. Hardware is advancing all the time, and with constant progress towards larger and more fault-tolerant quantum computers, it now seems very foreseeable that they’ll soon find a role in many industries. There are many functions they’ll never be well-suited to, and there’ll probably never […]
A 250-Mile Quantum Video Call
Researchers from the Universities of Bristol and Cambridge, operating as part of the UK’s Quantum Network and Quantum Communications Hub, have demonstrated long-distance quantum communication between their two cities using quantum key distribution, including a live video conference. Their results were presented recently at Optical Fiber Communications 2025 in San Francisco. This is the latest […]
