One-way quantum computing allows any quantum algorithm to be implemented easily using just measurements. The difficult part is creating the universal resource, a cluster state, on which the measurements are made. We propose a scalable method that uses a single, multimode optical parametric oscillator (OPO). The method is very efficient and generates a continuous-variable cluster state, universal for quantum computation, with quantum information encoded in the quadratures of the optical…

The optical frequency comb as a one-way quantum computer

In the one-way model of quantum computing, quantum algorithms are implemented using only measurements on an entangled initial state. Much of the hard work is done upfront when creating this universal

One-way quantum computing with arbitrarily large time-frequency continuous-variable cluster states from a single optical parametric oscillator

A generalized measurement protocol is introduced to enable improved computational performance on this entanglement resource and create a scalable architecture in which a single optical parametric oscillator and simple interferometer entangle into a computationally universal continuous-variable cluster state.

Hypercubic cluster states in the phase-modulated quantum optical frequency comb

We propose and fully analyze the simplest technique to date to generate light-based universal quantum computing resources, namely 2D, 3D and, in general, n-hypercubic cluster states. The technique

Quantum spin models for measurement-based quantum computation

Measurement-based quantum computation is different from other approaches for quantum computation, in that everything needs to be done is only local measurement on a certain entangled state. It thus

Hyper-parallel photonic quantum computation with coupled quantum dots

This work constructs a deterministic hyper-controlled-not (hyper-CNOT) gate operating on both the spatial-mode and the polarization DOFs of a two-photon system simultaneously, by exploiting the giant optical circular birefringence induced by quantum-dot spins in double-sided optical microcavities as a result of cavity quantum electrodynamics (QED).

Optical hybrid approaches to quantum information

This article reviews recent hybrid approaches to optical quantum information processing, in which both discrete and continuous degrees of freedom are exploited, potentially adding weak or measurement-induced nonlinearities to the toolbox.

Parallel Photonic Quantum Computation Assisted by Quantum Dots in One-Side Optical Microcavities

These hyper-CNOT gates show that the quantum states of two DOFs can be viewed as independent qubits without requiring auxiliary DOFs in theory, which can reduce the quantum resources by half for quantum applications with large qubit systems, such as the quantum Shor algorithm.

One‐way Quantum Computation

This chapter provides an introduction to one-way quantum computation, and several of the techniques one can use to describe it, and introduces graph and cluster states and develop a notation for general single-qubit measurements.



A one-way quantum computer.

A scheme of quantum computation that consists entirely of one-qubit measurements on a particular class of entangled states, the cluster states, which are thus one-way quantum computers and the measurements form the program.
