About MeKanav Setia is a graduate student in the Whitfield Group that spends most of his time working with algorithms for quantum computers. Recently, he has been working on simulating fermions on a quantum computer, a problem that he calls "fascinating" and takes up most of his time."
Simulating quantum systems on classical computers requires exponential resources which motivates quantum simulation as a major application of quantum computing. Present quantum computers often work with qubits as their computational units which are distinguishable entities. To use qubits to simulate fermionic particles, which are indistinguishable, it is required to first map the quantum state of the particles to the state of the qubits. Jordan-Wigner and Bravyi-Kitaev algorithms are used to do this. I have been working with my adviser on an alternate algorithm which was first suggested by Bravyi and Kitaev under the name Super-fast simulation of fermions. The analytical model for Bravyi-Kitaev Super Fast (BKSF) model shows that given the interaction between the fermions is local, fermionic operators in BKSF scale much better compared to other algorithms. We have already validated the BKSF model with Jordan-Wigner in Matlab. This has been done for hydrogen molecule in the minimal basis set. The hydrogen example has turned out to be expensive in BKSF. Our next step is to find a smallest molecule where BKSF will be better.
