Fault-tolerant linear optical quantum computing with small-amplitude coherent States.
Quantum computing using two coherent states as a qubit basis is a proposed alternative architecture with lower overheads but has been questioned as a practical way of performing quantum computing due to the fragility of diagonal states with large coherent amplitudes. We show that using error correction only small amplitudes (alpha>1.2) are required for fault-tolerant quantum computing. We study...
متن کاملFault-tolerant quantum computing with color codes
We have just completed a thorough, multi-year study of fault-tolerant quantum computation with color codes. These codes are amazing—one way to think about them is as a family of codes which generalize the Steane code not by concatenation but by lattice embedding [1]. Our study of fault-tolerant computing with these codes is complete with analytic bounds, numerical simulations, multiple noise mo...
متن کاملFault-tolerant quantum computation with cluster states
The one-way quantum computing model introduced by Raussendorf and Briegel fPhys. Rev. Lett. 86, 5188 s2001dg shows that it is possible to quantum compute using only a fixed entangled resource known as a cluster state, and adaptive single-qubit measurements. This model is the basis for several practical proposals for quantum computation, including a promising proposal for optical quantum computa...
متن کاملQuantum multiplexing with optical coherent states
In this paper, we propose a novel quantum multiple access technique based on optical coherent states. The information of several coherent state optical qubits is combined into a single qudit, which is the superposition of almost orthogonal coherent states. The original information is encoded into a new Hilbert space with the help of a quantum multiplexer (QMUX) and then recovered at the other e...
متن کاملResource optimization for fault-tolerant quantum computing
Quantum computing offers the potential for efficiently solving otherwise classically difficult problems, with applications in material and drug design, cryptography, theoretical physics, number theory and more. However, quantum systems are notoriously fragile; interaction with the surrounding environment and lack of precise control constitute noise, which makes construction of a reliable quantu...
