Charge-insensitive qubit design derived from the Cooper pair box [PDF]
, 2007 Short dephasing times pose one of the main challenges in realizing a quantum computer. Different approaches have been devised to cure this problem for superconducting qubits, a prime example being the operation of such devices at optimal working points ...

Precision tomography of a three-qubit donor quantum processor in silicon [PDF]
Nature, 2021 Nuclear spins were among the first physical platforms to be considered for quantum information processing1,2, because of their exceptional quantum coherence3 and atomic-scale footprint. However, their full potential for quantum computing has not yet been

Single ion qubit with estimated coherence time exceeding one hour
Nature Communications, 2021 Realizing a long coherence time quantum memory is a major challenge of current quantum technology. Until now, the longest coherence-time of a single qubit was reported as 660 s in a single 171 Yb + ion-qubit through the technical developments of ...

Encoding a logical qubit into physical qubits [PDF]
Physical Review A, 2005 We propose two protocols to encode a logical qubit into physical qubits relying on common types of qubit-qubit interactions in as simple forms as possible. We comment on its experimental implementation in several quantum computing architectures, e.g.

Tackling the Qubit Mapping Problem for NISQ-Era Quantum Devices [PDF]
International Conference on Architectural Support for Programming Languages and Operating Systems, 2018 Due to little considerations in the hardware constraints, e.g., limited connections between physical qubits to enable two-qubit gates, most quantum algorithms cannot be directly executed on the Noisy Intermediate-Scale Quantum (NISQ) devices. Dynamically
