From transistor to trapped-ion computers for quantum chemistry
(Nature Publishing Group, 2014-01)
Over the last few decades, quantum chemistry has progressed through the development of computational methods based on modern digital computers. However, these methods can hardly fulfill the exponentially-growing resource ...
A continued fraction based approach for the Two-photon Quantum Rabi Model
(Nature Publishing, 2019-03-11)
We study the Two Photon Quantum Rabi Model by way of its spectral functions and survival probabilities. This approach allows numerical precision with large truncation numbers, and thus exploration of the spectral collapse. ...
Measurement-Based Adaptation Protocol with Quantum Reinforcement Learning in a Rigetti Quantum Computer
(MDPI, 2020-05-19)
We present an experimental realisation of a measurement-based adaptation protocol with quantum reinforcement learning in a Rigetti cloud quantum computer. The experiment in this few-qubit superconducting chip faithfully ...
Multiqubit and multilevel quantum reinforcement learning with quantum technologies
(Public Library Science, 2018-07-19)
We propose a protocol to perform quantum reinforcement learning with quantum technologies. At variance with recent results on quantum reinforcement learning with superconducting circuits, in our current protocol coherent ...
Quantum Simulation Of The Quantum Rabi Model In A Trapped Ion
(American Physical Society, 2018-04-30)
The quantum Rabi model, involving a two-level system and a bosonic field mode, is arguably the simplest and most fundamental model describing quantum light-matter interactions. Historically, due to the restricted parameter ...
Invited Article: Quantum Memristors in Quantum Photonics
(American Institute Of Physics, 2018-08)
We propose a method to build quantum memristors in quantum photonic platforms. We first design an effective beam splitter, which is tunable in real time, by means of a Mach-Zehnder-type array with two equal 50:50 beam ...
Quantum Artificial Life in an IBM Quantum Computer
(Nature Publishing, 2018-10-04)
We present the first experimental realization of a quantum artificial life algorithm in a quantum computer. The quantum biomimetic protocol encodes tailored quantum behaviors belonging to living systems, namely, self-replication, ...
Quantum Memristors With Superconducting Circuits
(Nature Publishing Group, 2017-02-14)
Memristors are resistive elements retaining information of their past dynamics. They have garnered substantial interest due to their potential for representing a paradigm change in electronics, information processing and ...
Entanglement of superconducting qubits via acceleration radiation
(Nature Publishing, 2017-04-06)
We show that simulated relativistic motion can generate entanglement between artificial atoms and protect them from spontaneous emission. We consider a pair of superconducting qubits coupled to a resonator mode, where the ...
Secure quantum remote state preparation of squeezed microwave states
(Nature Publishing, 2019-06-13)
Quantum communication protocols based on nonclassical correlations can be more efficient than known classical methods and offer intrinsic security over direct state transfer. In particular, remote state preparation aims ...
