Any Clifford+T circuit can be controlled with constant T-depth overhead
Isaac H. Kim, Tuomas Laakkonen
Since an n-qubit circuit consisting of CNOT gates can have up to CNOT gates, it is natural to expect that Toffoli gates are needed to apply a cont…
Efficient simulation of logical magic state preparation protocols
Samyak Surti, Lucas Daguerre, Isaac H. Kim
Developing space- and time-efficient logical magic state preparation protocols will likely be an essential step towards building a large-scale fault-tolerant quantum computer. Moti…
Sdim: A Qudit Stabilizer Simulator
Adeeb Kabir, Steven Nguyen, Sohan Ghosh +5
Quantum computers have steadily improved over the last decade, but developing fault-tolerant quantum computing (FTQC) techniques, required for useful, universal computation remains…
A quantum algorithm for modular flow
Ian T. Lim, Isaac H. Kim
Entanglement is a defining property of quantum systems. For a subsystem of a larger quantum system, one can formally define an operator known as the modular Hamiltonian, which is c…
Catalytic -rotations in constant -depth
Isaac H. Kim
We show that the -depth of any single-qubit -rotation can be reduced to if a certain catalyst state is available. To achieve an -approximation, it suffices to have a c…
Experimental Demonstration of High-Fidelity Logical Magic States from Code Switching
Lucas Daguerre, Robin Blume-Kohout, Natalie C. Brown +2
Preparation of high-fidelity logical magic states has remained as a necessary but daunting step towards building a large-scale fault-tolerant quantum computer. One approach is to f…
