A single-number metric, quantum volume, that can be measured using a concrete protocol on near-term quantum computers of modest size, and measured on several state-of-the-art transmon devices, finding values as high as 16.5%.
Colloquium: Stimulating uncertainty: Amplifying the quantum vacuum with superconducting circuits
The ability to generate particles from the quantum vacuum is one of the most pro- found consequences of Heisenberg's uncertainty principle. Although the significance of vacuum fluctuations can be…
The trilinear Hamiltonian: a zero-dimensional model of Hawking radiation from a quantized source
We investigate a quantum parametric amplifier with dynamical pump mode, viewed as a zero-dimensional model of Hawking radiation from an evaporating black hole. We derive the conditions under which…
Challenges and Opportunities of Near-Term Quantum Computing Systems
An IBM-specific perspective of the facets associated with these systems, including quantum software, cloud access, benchmarking quantum systems, error correction and mitigation in such systems, understanding the complexity of quantum circuits, and how early quantum applications can run on near-term quantum computers are highlighted.
Analogue Hawking radiation in a dc-SQUID array transmission line.
A superconducting transmission line formed from an array of direct-currentsuperconducting quantum interference devices for investigating analogue Hawking radiation by biasing the array with a space-time varying flux leads to an effective metric with a horizon.
Nonclassical mechanical states in an optomechanical micromaser analog

- 20 August 2013
We show that quantum states of a mechanical oscillator can be generated in an optomechanical analogue of the micromaser, in absence of any atom-like subsystem. Sub-Poissonian oscillator limit-cycles…
Scalable Mitigation of Measurement Errors on Quantum Computers
We present a method for mitigating measurement errors on quantum computing platforms that does not form the full assignment matrix, or its inverse, and works in a subspace defined by the noisy input…
Non-equilibrium Landauer transport model for Hawking radiation from a black hole
We propose that the Hawking radiation energy and entropy flow rates from a black hole can be viewed as a one-dimensional (1D), non-equilibrium Landauer transport process. Support for this viewpoint…
