The side effects of quantum error correction and how to cope with them

It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that, unexpectedly, the approach can also give rise to inaccurate and misleading results — and shows how to rectify these shortcomings. Quantum systems can interact with one another and with their surroundings in ways that […]

New world record for qubit storage

A UNIGE team in Geneva, Switzerland, has succeeded in storing a quantum bit for 20 milliseconds. A duration that had never before been achieved by a solid-state quantum memory. Long-duration quantum memories for photonic qubits are essential components for achieving long-distance quantum networks and repeaters. The mapping of optical states onto coherent spin-waves in rare […]

Silicon quantum dots using CMOS technology

Solid-state quantum computers require classical electronics to control and readout individual qubits and to enable fast classical data processing. Integrating both subsystems at deep cryogenic temperatures, where solid- state quantum processors operate best, may solve some major scaling challenges, such as system size and Input/Output (I/O) data management. Spin qubits in silicon Quantum Dots (QDs) […]

ETH boosts Quantum Research in Switzerland

ETH Zurich in Switzerland intends to further expand its leading position in quantum research, and so it is planning a highly specialised physics laboratory building on the Hönggerberg campus. A generous donation from ETH alumnus and ETH Honorary Councillor Martin Haefner (40 million Swiss francs to the ETH Foundation) is now the key step to […]
