Quantum Error Correction and Orthogonal Geometry [PDF]
, 1996 A group theoretic framework is introduced that simplifies the description of known quantum error-correcting codes and greatly facilitates the construction of new examples.

Quantum information processing using Josephson junctions coupled through cavities [PDF]
, 2003 Josephson junctions have been shown to be a promising solid-state system for implementation of quantum computation. The significant two-qubit gates are generally realized by the capacitive coupling between the nearest neighbour qubits.

Conference on Lasers and Electro-Optics, 2019 AbstractFree‐electron interactions with laser‐driven nearfields can quantize the electrons’ energy spectrum and provide control over this quantized degree of freedom. The study proposes to use such interactions to promote free electrons as carriers of quantum information and show how to create a qubit on a free electron, which holds promise for ...

The Small Stellated Dodecahedron Code and Friends [PDF]
, 2018 We explore a distance-3 homological CSS quantum code, namely the small stellated dodecahedron code, for dense storage of quantum information and we compare its performance with the distance-3 surface code.

Two-dimensional semiconductors pave the way towards dopant-based quantum computing
Beilstein Journal of Nanotechnology, 2018 Since the proposal in 1998 to build a quantum computer using dopants in silicon as qubits, much progress has been made in the nanofabrication of semiconductors and the control of charge and spins in single dopants.

Coupling Superconducting Qubits via a Cavity Bus
, 2007 Superconducting circuits are promising candidates for constructing quantum bits (qubits) in a quantum computer; single-qubit operations are now routine, and several examples of two qubit interactions and gates having been demonstrated.

Bell inequality, Bell states and maximally entangled states for n qubits
, 1998 First, we present a Bell type inequality for n qubits, assuming that m out of the n qubits are independent. Quantum mechanics violates this inequality by a ratio that increases exponentially with m.
