Multi-zone trapped-ion qubit control in an integrated photonics QCCD device
Carmelo Mordini, Alfredo Ricci Vasquez, Yuto Motohashi +6
Multiplexed operations and extended coherent control over multiple trapping sites are fundamental requirements for a trapped-ion processor in a large scale architecture. Here we de…
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…
Coherent Control of Trapped Ion Qubits with Localized Electric Fields
R. Srinivas, C. M. Löschnauer, M. Malinowski +8
We present a new method for coherent control of trapped ion qubits in separate interaction regions of a multi-zone trap by simultaneously applying an electric field and a spin-depe…
Control of an atomic quadrupole transition in a phase-stable standing wave
Alfredo Ricci Vasquez, Carmelo Mordini, Chloé Vérnière +6
Using a single calcium ion confined in a surface-electrode trap, we study the interaction of electric quadrupole transitions with a passively phase-stable optical standing wave fie…
Generation of a maximally entangled state using collective optical pumping
M. Malinowski, C. Zhang, V. Negnevitsky +7
We propose and implement a novel scheme for dissipatively pumping two qubits into a singlet Bell state. The method relies on a process of collective optical pumping to an excited l…
Integrated optical multi-ion quantum logic
Karan K. Mehta, Chi Zhang, Maciej Malinowski +3
Practical and useful quantum information processing (QIP) requires significant improvements with respect to current systems, both in error rates of basic operations and in scale. I…
Probing the limits of correlations in an indivisible quantum system
M. Malinowski, C. Zhang, F. M. Leupold +3
We employ a trapped ion to study quantum contextual correlations in a single qutrit using the 5-observable KCBS inequality, which is arguably the most fundamental non-contextuality…
Sustained state-independent quantum contextual correlations from a single ion
F. M. Leupold, M. Malinowski, C. Zhang +4
We use a single trapped-ion qutrit to demonstrate the violation of an input-state-independent non-contextuality inequality using a sequence of randomly chosen quantum non-demolitio…
