Superconducting circuits rank among some of the most interesting architectures for the implementation of quantum information processing devices. The recently proposed 0- π qubit (Brooks et al 2013 Phys. Rev. A 87 52306) promises increased protection

We propose a time-delayed feedback control scheme for open quantum systems that can dramatically reduce the time to reach steady state. No measurement is performed in the feedback loop, and we suggest a simple all-optical implementation for a cavity

Bosonic quantum error-correcting codes offer a viable direction towards reducing the hardware overhead required for fault-tolerant quantum information processing. A broad class of bosonic codes, namely rotation-symmetric codes, can be characterized b

The development of robust architectures capable of large-scale fault-tolerant quantum computation should consider both their quantum error-correcting codes and the underlying physical qubits upon which they are built, in tandem. Following this design

Quantum information: Microwave quantum computer Microwaves, familiar from our everyday lives, can be used to perform quantum computation. We show how this is possible using a quantum electronic device called a Josephson Travelling Wave Parametric Amp

Quantum annealing aims at solving optimization problems mapped to Ising interactions between neighbouring spins, but it is crucial to implement it in a noise-resilient way. Here the authors propose a network of all-to-all connected driven Kerr-nonlin

The Gottesman-Kitaev-Preskill (GKP) code was proposed in 2001 by Daniel Gottesman, Alexei Kitaev, and John Preskill as a way to encode a qubit in an oscillator. The GKP codewords are coherent superpositions of periodically displaced squeezed vacuum s

We analyze a readout scheme for Majorana qubits based on dispersive coupling to a resonator. We consider two variants of Majorana qubits: the Majorana transmon and the Majorana box qubit. In both cases, the qubit-resonator interaction can produce siz

Bosonic rotation codes, introduced here, are a broad class of bosonic error-correcting codes based on phase-space rotation symmetry. We present a universal quantum computing scheme applicable to a subset of this class—number-phase codes—which inc
