The surface code with a twist
Theodore J. Yoder, Isaac H. Kim
The surface code is one of the most successful approaches to topological quantum error-correction. It boasts the smallest known syndrome extraction circuits and correspondingly lar…
Fixed-Point Adiabatic Quantum Search
Alexander M. Dalzell, Theodore J. Yoder, Isaac L. Chuang
Fixed-point quantum search algorithms succeed at finding one of target items among total items even when the run time of the algorithm is longer than necessary. While the f…
Hamiltonian Simulation with Optimal Sample Complexity
Shelby Kimmel, Cedric Yen-Yu Lin, Guang Hao Low +2
We investigate the sample complexity of Hamiltonian simulation: how many copies of an unknown quantum state are required to simulate a Hamiltonian encoded by the density matrix of…
Heisenberg scaling of imaging resolution by coherent enhancement
Robert McConnell, Guang Hao Low, Theodore J. Yoder +4
Classical imaging works by scattering photons from an object to be imaged, and achieves resolution scaling as , with the imaging time. By contrast, the laws of quan…
The methodology of resonant equiangular composite quantum gates
Guang Hao Low, Theodore J. Yoder, Isaac L. Chuang
The creation of composite quantum gates that implement quantum response functions dependent on some parameter of interest is often more of an art than a science. T…
Universal fault-tolerant gates on concatenated stabilizer codes
Theodore J. Yoder, Ryuji Takagi, Isaac L. Chuang
It is an oft-cited fact that no quantum code can support a set of fault-tolerant logical gates that is both universal and transversal. This no-go theorem is generally responsible f…
