Spectral functions on a quantum computer through system-environment interaction
Etienne Granet, Ramil Nigmatullin, David T. Stephen +1
Spectral functions measured with angle-resolved photoemission spectroscopy (ARPES) provide key insight to elucidate the band structure of materials. Comparison with theory requires…
Directly estimating the fidelity of measurement-based quantum computation
David T. Stephen, Michael Foss-Feig
In measurement-based quantum computation (MBQC), quantum circuits are implemented using adaptive measurements on an entangled resource state. In practice, the resource state will a…
Superconducting pairing correlations on a trapped-ion quantum computer
Etienne Granet, Sheng-Hsuan Lin, Kevin Hémery +31
The Fermi-Hubbard model is the starting point for the simulation of many strongly correlated materials, including high-temperature superconductors, whose modelling is a key motivat…
Certified randomness amplification by dynamically probing remote random quantum states
Minzhao Liu, Pradeep Niroula, Matthew DeCross +49
Cryptography depends on truly unpredictable numbers, but physical sources emit biased or correlated bits. Quantum mechanics enables the amplification of imperfect randomness into n…
