By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...

By reducing the ratio, quantum computers would need a thousand times fewer qubits, making them significantly easier to build and scale, while also requiring less power and computational ...

One half of the Physics World 2024 Breakthrough of the Year has been awarded to Hartmut Neven and colleagues at Google Quantum AI and their collaborators for ...

A University of Sydney quantum physicist has developed a new approach to quantum error correction - using lattice gauge theory - that could significantly reduce the number of physical qubits required ...
