Realization of quantum signal processing on a noisy quantum computer [PDF]
npj Quantum Information, 2023 Quantum signal processing (QSP) is a powerful toolbox for the design of quantum algorithms and can lead to asymptotically optimal computational costs. Its realization on noisy quantum computers without fault tolerance, however, is challenging because it ...

Exact and efficient Lanczos method on a quantum computer [PDF]
Quantum, 2022 We present an algorithm that uses block encoding on a quantum computer to exactly construct a Krylov space, which can be used as the basis for the Lanczos method to estimate extremal eigenvalues of Hamiltonians.

Measurement-induced quantum phases realized in a trapped-ion quantum computer [PDF]
Nature Physics, 2021 Many-body open quantum systems balance internal dynamics against decoherence and measurements induced by interactions with an environment1,2. Quantum circuits composed of random unitary gates with interspersed projective measurements represent a minimal ...

Quantum computing for quantum tunneling [PDF]
Physical Review D, 2021 We demonstrate how quantum field theory problems can be embedded on quantum annealers. The general method we use is a discretisation of the field theory problem into a general Ising model, with the continuous field values being encoded into Ising spin chains.
