Proposal for high-fidelity quantum simulation using a hybrid dressed state
Jianming Cai, Itsik Cohen, Alex Retzker +1
A fundamental goal of quantum technologies concerns the exploitation of quantum coherent dynamics for the realisation of novel quantum applications such as quantum computing, quant…
Parameter estimation with efficient photodetectors
Tuvia Gefen, David A. Herrera-Martí, Alex Retzker
Current parameter estimation techniques rely on photodetectors which have low brightness and thus are based on gathering averaged statistics. Recently it was claimed that perfect p…
Simulating the Haldane Phase in Trapped Ion Spins Using Optical Fields
I. Cohen, P. Richerme, Z. -X. Gong +2
We propose to experimentally explore the Haldane phase in spin-one XXZ antiferromagnetic chains using trapped ions. We show how to adiabatically prepare the ground states of the Ha…
Multi-Qubit Gate with Trapped Ions for Microwave and Laser-Based Implementation
Itsik Cohen, Seb Weidt, Winfried K. Hensinger +1
A proposal for a phase gate and a Mølmer-Sørensen (MS) gate in the dressed state basis is presented. In order to perform the multi-qubit interaction, a strong magnetic field gradie…
Optical hyperpolarization of 13C nuclear spins in nanodiamond ensembles
Q. Chen, I. Schwarz, F. Jelezko +2
Here we propose and analyse in detail protocols that can achieve rapid hyperpolarization of 13C nuclear spins in randomly oriented ensembles of nanodiamonds at room temperature. Ou…
