Variance reduction methods in the estimation of Pauli sums
Søren Fuglede Jørgensen, Rafael Emilio Barfknecht, Patrick Ettenhuber +1
Accurately estimating expectation values of quantum observables with as few measurements as possible is crucial to many quantum computing applications. We introduce a framework tha…
Fault-tolerant quantum computations of vibrational wave functions
Marco Majland, Rasmus Berg Jensen, Patrick Ettenhuber +3
Quantum computation of vibrational properties of molecules is a promising platform to obtain computational advantages for computational chemistry. However, fault-tolerant quantum c…
Impact of finite squeezing on near-term quantum computations using GKP qubits
Frederik K. Marqversen, Andreas B. Michelsen, Janus H. Wesenberg +1
We present the first detailed simulation of a measurement based quantum computation based on Gottesman-Kitaev-Preskill (GKP) qubits within a quad-rail lattice (QRL) cluster state i…
Performance analysis of GKP error correction
Frederik K. Marqversen, Janus H. Wesenberg, Nikolaj T. Zinner +1
Quantum error correction is essential for achieving fault-tolerant quantum computing. Gottesman-Kitaev-Preskill (GKP) codes are particularly effective at correcting continuous nois…
Taming quantum systems: A tutorial for using shortcuts-to-adiabaticity, quantum optimal control, and reinforcement learning
Callum W. Duncan, Pablo M. Poggi, Marin Bukov +2
Precise manipulation of quantum effects at the atomic and nanoscale has become an essential task in ongoing scientific and technological endeavours. Quantum control methods are thu…
Digital simulation of zero-temperature spontaneous symmetry breaking in a superconducting lattice processor
Chang-Kang Hu, Guixu Xie, Kasper Poulsen +11
Quantum simulators are ideal platforms to investigate quantum phenomena that are inaccessible through conventional means, such as the limited resources of classical computers to ad…
