Quantum simulation of lattice gauge theories coupled to fermionic matter via anyonic regularization
Mason L. Rhodes, Shivesh Pathak, Riley W. Chien
The optimal regularization of infinite-dimensional gauge-field degrees of freedom is a central open problem in the simulation of lattice gauge theories on quantum computers. Here,…
Putting fermions onto a digital quantum computer
Riley W. Chien, Mitchell L. Chiew, Brent Harrison +8
Quantum computers are expected to become a powerful tool for studying physical quantum systems. Consequently, a number of quantum algorithms for studying the physical properties of…
Encoding Majorana codes
Maryam Mudassar, Riley W. Chien, Daniel Gottesman
To implement a quantum error correction protocol, we first need a scheme to prepare our state in the correct subspace of the code, and this can be done using a unitary encoding cir…
Simulating quantum error mitigation in fermionic encodings
Riley W. Chien, Kanav Setia, Xavier Bonet-Monroig +2
The most scalable proposed methods of simulating lattice fermions on noisy quantum computers employ encodings that eliminate nonlocal operators using a constant factor more qubits…
Optimizing fermionic encodings for both Hamiltonian and hardware
Riley W. Chien, Joel Klassen
In this work we present a method for generating a fermionic encoding tailored to a set of target fermionic operators and to a target hardware connectivity. Our method uses brute fo…
Custom fermionic codes for quantum simulation
Riley W. Chien, James D. Whitfield
Simulating a fermionic system on a quantum computer requires encoding the anti-commuting fermionic variables into the operators acting on the qubit Hilbert space. The most familiar…
Analysis of Superfast Encoding Performance for Electronic Structure Simulations
Riley W. Chien, Sha Xue, Tarini S. Hardikar +2
In our recent work, we have examined various fermion to qubit mappings in the context of quantum simulation including the original Bravyi-Kitaev Superfast encoding (OSE) as well as…
