Spacetime-Efficient Low-Depth Quantum State Preparation with Applications
Kaiwen Gui, Alexander M. Dalzell, Alessandro Achille +2
We propose a novel deterministic method for preparing arbitrary quantum states. When our protocol is compiled into CNOT and arbitrary single-qubit gates, it prepares an -dimensi…
Optimized Quantum Program Execution Ordering to Mitigate Errors in Simulations of Quantum Systems
Teague Tomesh, Kaiwen Gui, Pranav Gokhale +4
Simulating the time evolution of a physical system at quantum mechanical levels of detail -- known as Hamiltonian Simulation (HS) -- is an important and interesting problem across…
Term Grouping and Travelling Salesperson for Digital Quantum Simulation
Kaiwen Gui, Teague Tomesh, Pranav Gokhale +4
Digital simulation of quantum dynamics by evaluating the time evolution of a Hamiltonian is the initially proposed application of quantum computing. The large number of quantum gat…
Measurement Cost for Variational Quantum Eigensolver on Molecular Hamiltonians
Pranav Gokhale, Frederic T. Chong
Variational Quantum Eigensolver (VQE) is a promising algorithm for near-term quantum machines. It can be used to estimate the ground state energy of a molecule by performing separa…
Minimizing State Preparations in Variational Quantum Eigensolver by Partitioning into Commuting Families
Pranav Gokhale, Olivia Angiuli, Yongshan Ding +5
Variational quantum eigensolver (VQE) is a promising algorithm suitable for near-term quantum machines. VQE aims to approximate the lowest eigenvalue of an exponentially sized matr…
