Robust Nonperturbative Trapped-Ion Quantum Logic
Luca Stefanescu, Florian Mintert
The paper proposes optimized driving schemes that exploit anharmonic motional dynamics to implement fast, high-fidelity entangling gates for trapped-ion qubits, while enhancing rob…
Multi-ion entangling gates mediated by spectrally unresolved modes
Modesto Orozco-Ruiz, Florian Mintert
Entangling interactions between distant qubits can be mediated via an additional degree of freedom. In conventional trapped-ion schemes, realizing a well-defined, coherent gate typ…
Fast thermal state preparation beyond native interactions
Alexander van Lomwel, Paul M. Schindler, Modesto Orozco-Ruiz +3
While questions on quantum simulation of ground state physics are mostly focussed on the realization of effective interactions, most work on quantum simulation of thermal physics e…
Amplitude-noise-resilient entangling gates for trapped ions
Nguyen H. Le, Modesto Orozco-Ruiz, Sahra A. Kulmiya +4
Noise resilience of quantum information processing is a crucial precondition to reach the fault-tolerance threshold. While resilience to many types of noise can be achieved through…
Robust implicit quantum control of interacting spin chains
Luca Stefanescu, Louis Edwards-Pratt, Jeremy O'Connor +3
Robust quantum control can achieve noise-resilience of quantum systems and quantum technological devices. While the need for noise-resilience grows with the number of fluctuating q…
Quantum control without quantum states
Modesto Orozco-Ruiz, Nguyen H. Le, Florian Mintert
We show that combining ideas from the fields of quantum invariants and of optimal control can be used to design optimal quantum control solutions without explicit reference to quan…
