Robust Nonperturbative Trapped-Ion Quantum Logic
Luca Stefanescu, Florian Mintert
Entangling gates of trapped ions are typically mediated by collective motional degrees of freedom. Weak coupling between qubit and motional degrees of freedom and the resulting har…
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…
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…
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…
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…
Generally noise-resilient quantum gates for trapped-ions
Modesto Orozco-Ruiz, Wasim Rehman, Florian Mintert
We present an entangling gate scheme for trapped-ion chains that achieves high-fidelity operations with excited motional states despite multiple error sources. Our approach incorpo…
Ion-trap quantum logic using long-wavelength radiation
Florian Mintert, Christof Wunderlich
A quantum information processor is proposed that combines experimental techniques and technology successfully demonstrated either in nuclear magnetic resonance experiments or with…
