I remember reading a paper that described how a quantum circuit on a large amount of qubits can be simulated by doing many runs on a smaller quantum computer. They used techniques from tensor networks. I believe it was published in PRL somewhere after 2018, but I haven't been able to find it again. It is not this paper: Computational Speedups Using Small Quantum Devices (Dunjko et al., 2018).
Does anybody know which paper I'm talking about it, or have I simply dreamt up the existence of this paper?
