Throughout our work, we show that compact and extended representations of the physics of QPS junctions can to a certain degree be mapped into one another, but for a variety of question, care has to be taken not to introduce spurious states into the description. In the quantum regime the ...
In general, the automated design procedures of experiments have much broader applications beyond quantum optical setups, and can be of importance for many scientific disciplines other than physics. 5. Conclusions We have shown that an LSTM-based neural network can be trained to successfully predict ...
However, quantum protocols realized so far are subject to a new class of attacks exploiting a mismatch between the quantum states or measurements implemented and their theoretical modelling, as demonstrated in numerous experiments3,4,5,6. Here we present the experimental realization of a complete ...
“What’s amazing is humans have been able to engineer a system to demonstrate one of the most exotic pieces of physics in the universe. And we expect to capitalize on this to do the almost unthinkable — to push towards a fault-tolerant quantum machine that will enable computation on an ...
Organizer: UC Santa Barbara, Kavli Institute for Theoretical Physics Abstract: The control of quantum many-body states of matter in solid-state systems with short strong classical laser pulses has seen a surge in the past decade. Time-resolved experiments on solid-state systems have made rapid ...

An interesting testing ground for such a comprehensive theory would naturally be the recent experiments probing the strong coupling of molecule vibrations to “picocavities” [20], formed by the presence of an adsorbed molecule between two metallic facets not even 1 nm apart. In this regime, the...
The short response to this question is that all we know about light (or anything else, for that matter) are the results of experiments, and that some kinds of experiments show that light behaves like particles, and that other experiments reveal light to have the properties of waves. For ...
Let us now provide more details on our experiments. The experimental setup is shown in Fig.3. The coherent light pulses are generated using a continuous wave laser source emitting light at 1560 nm followed by an amplitude modulator, at a rate of 50 kHz and with a pulse duration of 10...
However, compared to the RCS and QMC experiments, the VQE simulations with tens of qubits would be significantly more challenging for quantum hardware in that: (1) the circuit depth scales quickly up to 103 or even more as the number of qubits increases10 and (2) the nonlinear optimization ...
