Two-qubit gates in a trapped-ion quantum computer by engineering motional modes
Ming Li, Jason Amini, Yunseong Nam
A global race towards developing a gate-based, universal quantum computer that one day promises to unlock the never before seen computational power has begun and the biggest challe…
Efficient, stabilized two-qubit gates on a trapped-ion quantum computer
Reinhold Blümel, Nikodem Grzesiak, Nhung H. Nguyen +5
Quantum computing is currently limited by the cost of two-qubit entangling operations. In order to scale up quantum processors and achieve a quantum advantage, it is crucial to eco…
Generalized Hamiltonian to describe imperfections in ion-light interaction
Ming Li, Kenneth Wright, Neal C. Pisenti +3
We derive a general Hamiltonian that governs the interaction between an -ion chain and an externally controlled laser field, where the ion motion is quantized and the laser fiel…
Efficient Arbitrary Simultaneously Entangling Gates on a trapped-ion quantum computer
Nikodem Grzesiak, Reinhold Blümel, Kristin Beck +7
Efficiently entangling pairs of qubits is essential to fully harness the power of quantum computing. Here, we devise an exact protocol that simultaneously entangles arbitrary pairs…
