Gapped two-body Hamiltonian for continuous-variable quantum computation.

We introduce a family of Hamiltonian systems for measurement-based quantum computation with continuous variables. The Hamiltonians (i) are quadratic, and therefore two body, (ii) are of short range, (iii) are frustration-free, and (iv) possess a constant energy gap proportional to the squared inverse of the squeezing. Their ground states are the celebrated Gaussian graph states, which are unive...

Continuous-variable blind quantum computation.

Blind quantum computation is a secure delegated quantum computing protocol where Alice, who does not have sufficient quantum technology at her disposal, delegates her computation to Bob, who has a fully fledged quantum computer, in such a way that Bob cannot learn anything about Alice's input, output, and algorithm. Protocols of blind quantum computation have been proposed for several qudit mea...

Measurement-based quantum computer in the gapped ground state of a two-body Hamiltonian.

We propose a scheme for a ground-code measurement-based quantum computer, which enjoys two major advantages. First, every logical qubit is encoded in the gapped degenerate ground subspace of a spin-1 chain with nearest-neighbor two-body interactions, so that it equips built-in robustness against noise. Second, computation is processed by single-spin measurements along multiple chains dynamicall...

From Qubits to Continuous–Variable Quantum Computation

By encoding a qudit in a harmonic oscillator and investigating the d → ∞ limit, we give an entirely new realization of continuous–variable quantum computation. The generalized Pauli group is generated by number and phase operators for harmonic oscillators. The use of continuous–variable (CV) quantum computing allows information to be encoded and processed much more compactly and efficiently tha...

Gate sequence for continuous variable one-way quantum computation

Measurement-based one-way quantum computation using cluster states as resources provides an efficient model to perform computation and information processing of quantum codes. Arbitrary Gaussian quantum computation can be implemented sufficiently by long single-mode and two-mode gate sequences. However, continuous variable gate sequences have not been realized so far due to an absence of cluste...
