Quantum metrology
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
We point out a general framework that encompasses most cases in which quantum effects enable an increase in precision when estimating a parameter (quantum metrology). The typical q…
Macroscopic Entanglement by Entanglement Swapping
Stefano Pirandola, David Vitali, Paolo Tombesi +1
We present a scheme for entangling two micromechanical oscillators. The scheme exploits the quantum effects of radiation pressure and it is based on a novel application of entangle…
Quantum limits to the measurement of spacetime geometry
Seth Lloyd
This letter analyzes the limits that quantum mechanics imposes on the accuracy to which spacetime geometry can be measured. By applying the physics of computation to ensembles of c…
Decoherent histories and generalized measurements
Seth Lloyd
The theory of decoherent histories allows one to talk of the behavior of quantum systems in the absence of measurement. This paper generalizes the idea of decoherent histories to a…
Convergence Conditions for Random Quantum Circuits
Joseph Emerson, Etera Livine, Seth Lloyd
Efficient methods for generating pseudo-randomly distributed unitary operators are needed for the practical application of Haar distributed random operators in quantum communicatio…
A theory of quantum gravity based on quantum computation
Seth Lloyd
This paper proposes a method of unifying quantum mechanics and gravity based on quantum computation. In this theory, fundamental processes are described in terms of pairwise intera…
