Four- and six-photon stimulated Raman transitions for coherent qubit and qudit operations
Gabriel J. Gregory, Evan R. Ritchie, Alex Quinn +4
Quantum computers are typically composed of an array of two-level systems, or qubits, encoded in some information carrier, such as an electron, photon, or quantized circuit. The si…
Spontaneous Raman scattering out of a metastable atomic qubit
I. D. Moore, A. Quinn, J. O'Reilly +5
Metastable qubits in atomic systems can enable large-scale quantum computing by simplifying hardware requirements and adding efficient erasure conversion to the pre-existing toolbo…
High-fidelity entanglement of metastable trapped-ion qubits with integrated erasure conversion
A. Quinn, G. J. Gregory, I. D. Moore +6
Today's most advanced ion trap quantum computers have significant overhead due to the need for dual-species operation. Looking ahead, logical qubit register sizes will be limited b…
Scalable, high-fidelity all-electronic control of trapped-ion qubits
C. M. Löschnauer, J. Mosca Toba, A. C. Hughes +10
The central challenge of quantum computing is implementing high-fidelity quantum gates at scale. However, many existing approaches to qubit control suffer from a scale-performance…
Two-mode squeezing and SU(1,1) interferometry with trapped ions
J. Metzner, A. Quinn, S. Brudney +4
We experimentally implement circuits of one and two mode operations on two motional modes of a single trapped ion. This is achieved by implementing the required displacement, squee…
How to wire a 1000-qubit trapped ion quantum computer
M. Malinowski, D. T. C. Allcock, C. J. Ballance
One of the most formidable challenges of scaling up quantum computers is that of control signal delivery. Today's small-scale quantum computers typically connect each qubit to one…
