Calculating the Single-Particle Many-body Green's Functions via the Quantum Singular Value Transform Algorithm
Alexis Ralli, Gabriel Greene-Diniz, David Muñoz Ramo +1
The Quantum Singular Value Transformation (QSVT) is a technique that provides a unified framework for describing many of the quantum algorithms discovered to date. We implement a n…
Simulating non-unitary dynamics using quantum signal processing with unitary block encoding
Hans Hon Sang Chan, David Muñoz Ramo, Nathan Fitzpatrick
We adapt a recent advance in resource-frugal quantum signal processing - the Quantum Eigenvalue Transform with Unitary matrices (QET-U) - to explore non-unitary imaginary time evol…
Non-unitary Trotter circuits for imaginary time evolution
Chiara Leadbeater, Nathan Fitzpatrick, David Muñoz Ramo +1
We propose an imaginary time equivalent of the well-established Pauli gadget primitive for Trotter-decomposed real time evolution, using mid-circuit measurements on a single ancill…
