Hidden Inverses: Coherent Error Cancellation at the Circuit Level
Bichen Zhang, Swarnadeep Majumder, Pak Hong Leung +6
Coherent gate errors are a concern in many proposed quantum computing architectures. These errors can be effectively handled through composite pulse sequences for single-qubit gate…
Two-qubit entangling gates within arbitrarily long chains of trapped ions
Kevin A. Landsman, Yukai Wu, Pak Hong Leung +5
Ion trap systems are a leading platform for large scale quantum computers. Trapped ion qubit crystals are fully-connected and reconfigurable, owing to their long range Coulomb inte…
Entangling an arbitrary pair of qubits in a long ion crystal
Pak Hong Leung, Kenneth R. Brown
It is well established that the collective motion of ion crystals can be used as a quantum bus for multi-qubit entanglement. However, as the number of ions increases, it becomes di…
Robust two-qubit gates in a linear ion crystal using a frequency-modulated driving force
Pak Hong Leung, Kevin A. Landsman, Caroline Figgatt +3
In an ion trap quantum computer, collective motional modes are used to entangle two or more qubits in order to execute multi-qubit logical gates. Any residual entanglement between…
