Improved Accuracy for Trotter Simulations Using Chebyshev Interpolation
Gumaro Rendon, Jacob Watkins, Nathan Wiebe
Quantum metrology allows for measuring properties of a quantum system at the optimal Heisenberg limit. However, when the relevant quantum states are prepared using digital Hamilton…
Controlled Gate Networks: Theory and Application to Eigenvalue Estimation
Max Bee-Lindgren, Zhengrong Qian, Matthew DeCross +5
We introduce a new scheme for quantum circuit design called controlled gate networks. Rather than trying to reduce the complexity of individual unitary operations, the new strategy…
Time Dependent Hamiltonian Simulation Using Discrete Clock Constructions
Jacob Watkins, Nathan Wiebe, Alessandro Roggero +1
Compared with time independent Hamiltonians, the dynamics of generic quantum Hamiltonians are complicated by the presence of time ordering in the evolution operator. In the…
Demonstration of the Rodeo Algorithm on a Quantum Computer
Zhengrong Qian, Jacob Watkins, Gabriel Given +3
The rodeo algorithm is an efficient algorithm for eigenstate preparation and eigenvalue estimation for any observable on a quantum computer. This makes it a promising tool for stud…
Rodeo Algorithm for Quantum Computing
Kenneth Choi, Dean Lee, Joey Bonitati +2
We present a stochastic quantum computing algorithm that can prepare any eigenvector of a quantum Hamiltonian within a selected energy interval . In order to reduce the…
Projected Cooling Algorithm for Quantum Computation
Dean Lee, Joey Bonitati, Gabriel Given +6
In the current era of noisy quantum devices, there is a need for quantum algorithms that are efficient and robust against noise. Towards this end, we introduce the projected coolin…
Time fractals and discrete scale invariance with trapped ions
Dean Lee, Jacob Watkins, Dillon Frame +5
We show that a one-dimensional chain of trapped ions can be engineered to produce a quantum mechanical system with discrete scale invariance and fractal-like time dependence. By di…
