Ultrafast coherent excitation of an Ytterbium ion with single laser pulses
Kenji Shimizu, Jordan Scarabel, Elizabeth Bridge +6
Experimental realizations of two qubit entangling gates with trapped ions typically rely on addressing spectroscopically resolved motional sidebands, limiting gate speed to the sec…
Multi-GHz repetition rate, multi-watt average power, ultraviolet laser pulses for fast trapped-ion entanglement operations
M. I. Hussain, D. Heinrich, M. Guevara-Bertsch +4
The conventional approach to perform two-qubit gate operations in trapped ions relies on exciting the ions on motional sidebands with laser light, which is an inherently slow proce…
Ultra-fast two-qubit ion gate using sequences of resonant pulses
E. Torrontegui, D. Heinrich, M. I. Hussain +2
We propose a new protocol to implement ultra-fast two-qubit phase gates with trapped ions using spin-dependent kicks induced by resonant transitions. By only optimizing the allocat…
A -shaped Quantum Device for Implementation of Bell States in Solid State Environment
Aman Ullah, Mohammad Ali Mohammad, Mahmood Irtiza Hussain +1
Electronic spin-qubit is key ingredient for quantum information processing in a solid state environment. We present a -shaped two-qubit entanglement device capable of measuring…
Ultrafast coherent excitation of a Ca ion
D. Heinrich, M. Guggemos, M. Guevara-Bertsch +3
Trapped ions are a well-studied and promising system for the realization of a scalable quantum computer. Faster quantum gates would greatly improve the applicability of such a syst…
A single-atom 3D sub-attonewton force sensor
V. Blūms, M. Piotrowski, M. I. Hussain +5
All physical interactions are mediated by forces. Ultra-sensitive force measurements are therefore a crucial tool for investigating the fundamental physics of magnetic, atomic, qua…
Ultrafast, high repetition rate, ultraviolet, fiber based laser source: application towards Yb+ fast quantum-logic
Mahmood Irtiza Hussain, Matthew Joseph Petrasiunas, Christopher D. B. Bentley +6
Trapped ions are one of the most promising approaches for the realization of a universal quantum computer. Faster quantum logic gates could dramatically improve the performance of…
Geometric phase gate for entangling two Bose-Einstein condensates
Mahmood Irtiza Hussain, Ebubechukwu O. Ilo-Okeke, Tim Byrnes
We propose a method of entangling two spinor Bose-Einstein condensates using a geometric phase gate. The scheme relies upon only the ac Stark shift and a common controllable optica…
