Operational, gauge-free quantum tomography
Olivia Di Matteo, John Gamble, Chris Granade +2
As increasingly impressive quantum information processors are realized in laboratories around the world, robust and reliable characterization of these devices is now more urgent th…
Phase estimation with randomized Hamiltonians
Ian D. Kivlichan, Christopher E. Granade, Nathan Wiebe
Iterative phase estimation has long been used in quantum computing to estimate Hamiltonian eigenvalues. This is done by applying many repetitions of the same fundamental simulation…
Q# and NWChem: Tools for Scalable Quantum Chemistry on Quantum Computers
Guang Hao Low, Nicholas P. Bauman, Christopher E. Granade +9
Fault-tolerant quantum computation promises to solve outstanding problems in quantum chemistry within the next decade. Realizing this promise requires scalable tools that allow use…
Bayesian ACRONYM Tuning
John Gamble, Chris Granade, Nathan Wiebe
We provide an algorithm that uses Bayesian randomized benchmarking in concert with a local optimizer, such as SPSA, to find a set of controls that optimizes that average gate fidel…
Downfolding of many-body Hamiltonians using active-space models: extension of the sub-system embedding sub-algebras approach to unitary coupled cluster formalisms
Nicholas P. Bauman, Eric J. Bylaska, Sriram Krishnamoorthy +3
In this paper we outline the extension of recently introduced the sub-system embedding sub-algebras coupled cluster (SES-CC) formalism to the unitary CC formalism. In analogy to th…
Magnetic-field-learning using a single electronic spin in diamond with one-photon-readout at room temperature
Raffaele Santagati, Antonio A. Gentile, Sebastian Knauer +11
Nitrogen-vacancy (NV) centres in diamond are appealing nano-scale quantum sensors for temperature, strain, electric fields and, most notably, for magnetic fields. However, the cryo…
