Microsoft, Atom Computing, EeroQ update their quantum computing progress
Summary
Several companies, including Microsoft and Atom Computing, have shared updates on their progress in quantum computing. Microsoft improved its qubit devices by changing the materials used, leading to more stable quantum states, while Atom Computing is developing an architecture using atoms suspended by lasers for quantum calculations.Key Facts
- Microsoft works on topological qubits using thin superconducting wires on semiconductors.
- They replaced aluminum with lead and changed the semiconductor composition to improve qubit stability.
- The stability of quantum states improved from milliseconds to over 20 seconds with these material changes.
- Microsoft still needs to show control over qubits to perform calculations and connect them for error correction.
- Atom Computing uses lasers to hold atoms in place and uses their nuclear spins to perform quantum computing.
- Atom’s system includes storage, operation zones, and backup atoms to replace lost ones.
- Atom Computing’s hardware is accessible through Microsoft’s Azure Quantum Cloud service.
- Both companies focus on incremental progress toward making quantum computing practical and reliable.
