Scalable Quantum Networks Based on Few-qubit Registers
We describe and analyze a hybrid approach to scalable quantum computation based on an optically connected network of few-qubit quantum registers. We show that probabilistically connected ̄ve-qubit quantum registers su±ce for deterministic, fault-tolerant quantum computation even when state preparation, measurement, and entanglement generation all have substantial errors. We discuss requirements ...
متن کاملAlkaline-earth-metal atoms as few-qubit quantum registers.
We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom associated with individual alkaline-earth-metal atoms trapped in an optical lattice. Specifically, we describe how the qubits within each register can be individually manipulated and measured with subwavelength optical...
متن کاملSimulation of n-qubit quantum systems. I. Quantum registers and quantum gates
During recent years, quantum computations and the study of n-qubit quantum systems have attracted a lot of interest, both in theory and experiment. Apart from the promise of performing quantum computations, however, these investigations also revealed a great deal of difficulties which still need to be solved in practice. In quantum computing, unitary and non-unitary quantum operations act on a ...
متن کاملCSE 599d - Quantum Computing One Qubit, Two Qubit
Suppose that we are dealing with a quantum machine with simply two configurations for each cell. Such a setup is called a qubit. The word “qubit” was first used in the scientific literature by Ben Schumacher. In fact the word was suggested, in jest, in a conversation between Ben Schumacher and William Wootters. The jest, I believe, was that qubit would be pronounced just like “cubit,” which is ...
متن کاملOptimal Design of Two-Qubit Quantum Circuits
Current quantum computing hardware is unable to sustain quantum coherent operations for more than a handful of gate operations. Consequently, if near-term experimental milestones, such as synthesizing arbitrary entangled states, or performing fault-tolerant operations, are to be met, it will be necessary to minimize the number of elementary quantum gates used. In order to demonstrate non-trivia...
