The world’s first universal programmable quantum computer has been put through its paces. But the test program revealed significant hurdles that must be overcome before the device is ready for real ...
Quantum logic gates between different isotopic species are possible, can be driven by a relatively simple laser system, and can work with precision beyond the so-called 'fault-tolerant threshold' ...
When you create logic circuits using ICs or FPGAs, you can’t easily visualize their operation without special tools. But if you’ve ever seen a mechanical computer (like the Computer History Museum’s ...
Quantum exchange or swap gates are an important part of quantum computers with a large number of qubits. Researchers at ETH Zurich have developed a swap gate for qubits made of neutral atoms that is ...
Researchers at ETH Zurich have realized particularly stable quantum logical operations with qubits made of neutral atoms.
