A short note on the 0-fidelity
Karl Mayer
A recent article introduced a hierarchy of quantities called -fidelities that approximate the quantum process fidelity with increasing accuracy. The lowest approximation in this…
Certified Quantum Measurement of Majorana Fermions
Abu Ashik Md. Irfan, Karl Mayer, Gerardo Ortiz +1
We present a quantum self-testing protocol to certify measurements of fermion parity involving Majorana fermion modes. We show that observing a set of ideal measurement statistics…
Quantum gate teleportation between separated qubits in a trapped-ion processor
Yong Wan, Daniel Kienzler, Stephen D. Erickson +9
Large-scale quantum computers will require quantum gate operations between widely separated qubits. A method for implementing such operations, known as quantum gate teleportation (…
Quantum Process Fidelity Bounds from Sets of Input States
Karl Mayer, Emanuel Knill
We investigate the problem of bounding the quantum process fidelity given bounds on the fidelities between target states and the action of a process on a set of pure input states.…
