Rapid solution of problems by quantum computation

Deutsch, David, Jozsa, Richard·1992·Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences

Abstract

A class of problems is described which can be solved more efficiently by quantum computation than by any classical or stochastic method. The quantum computation solves the problem with certainty in exponentially less time than any classical deterministic computation.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The Deutsch-Jozsa algorithm is among the first examples to demonstrate that a quantum algorithm can achieve exponential speedup over any possible deterministic classical algorithms.

    “This algorithm is among the irst examples to demonstrate that a quantum algorithm can achieve exponentially speedup over any possible deterministic classical algorithms.”
  • The Deutsch-Jozsa algorithm can get the answer with only one-time evaluation to the oracle function whereas a deterministic classical computer would require 2^{n-1}+1 evaluations.

    “the quantum computer can get the answer with only one-time evaluation to the oracle function whereas a deterministic classical computer would require 2−1 + 1 times evaluations.”
  • BV algorithm is an extension to the Deutsch-Josza algorithm.

    “The Bernstein-Vazirani algorithm [13] is an extension to the Deutsch-Josza algorithm [33].”
  • Any physically allowed super-operator from k to l qubits can be described as a combination of adding k+l blank qubits, applying a unitary transformation on the 2k+l qubits, and then tracing out 2k qubits.

    “A lemma by Choi[16], and Hellwig and Kraus[45] asserts that any physically allowed super-operator from k to l qubits can be described as a combination of the above three operations: add k + l blank qubits, apply a unitary transformation on the 2 k + l qubits and then trace out 2 k qubits.”

  • Any super-operator that is trace-preserving and completely positive takes density matrices to density matrices.

    “It turns out that any super operator which satisfies these conditions indeed take density matrices to density matrices[45].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
