Dynamical Crystallization in the Dipole Blockade of Ultracold Atoms
(American Physical Society (APS), 2010)
We describe a method for controlling many-body states in extended ensembles of Rydberg atoms, forming crystalline structures during laser excitation of a frozen atomic gas. Specifically, we predict the existence of an ...
Optical magnetic detection of single-neuron action potentials using quantum defects in diamond
(Proceedings of the National Academy of Sciences, 2016)
Magnetic fields from neuronal action potentials (APs) pass largely unperturbed through biological tissue, allowing magnetic measurements of AP dynamics to be performed extracellularly or even outside intact organisms. To ...
Magnetic Resonance Detection of Individual Proton Spins Using Quantum Reporters
(American Physical Society (APS), 2014)
We demonstrate a method of magnetic resonance imaging with single nuclear-spin sensitivity under ambient conditions. Our method employs isolated electronic-spin quantum bits (qubits) as magnetic resonance “reporters” on ...
Electrical control of charged carriers and excitons in atomically thin materials
(Springer Science and Business Media LLC, 2018-01-15)
High-Resolution Magnetic Resonance Spectroscopy Using a Solid-State Spin Sensor
(Springer Nature, 2018-03)
Quantum systems that consist of solid-state electronic spins can be sensitive detectors of nuclear magnetic resonance (NMR) signals, particularly from very small samples. For example, nitrogen–vacancy centres in diamond ...
Quantum Kibble–Zurek mechanism and critical dynamics on a programmable Rydberg simulator
(Springer Nature, 2019-04)
Quantum phase transitions (QPTs) involve transformations between different states of matter that are driven by quantum fluctuations. These fluctuations play a dominant role in the quantum critical region surrounding the ...
Quantum Convolutional Neural Networks
(Springer Science and Business Media LLC, 2019-08-26)
Neural network-based machine learning has recently proven successful for many complex applications ranging from image recognition to precision medicine. However, its direct application to problems in quantum physics is ...
A method for directional detection of dark matter using spectroscopy of crystal defects
(American Physical Society (APS), 2017-08-15)
We propose a method to identify the direction of an incident weakly interacting massive particle (WIMP) via induced nuclear recoil. Our method is based on spectroscopic interrogation of quantum defects in macroscopic ...
Experimental Demonstration of Memory-Enhanced Quantum Communication
(Springer Science and Business Media LLC, 2020-03-23)
The ability to communicate quantum information over long distances is of central importance in quantum science and engineering. While some applications of quantum communication such as secure quantum key distribution (QKD) ...
High-Temperature Superfluidity of Fermionic Atoms in Optical Lattices
(American Physical Society (APS), 2002)
Fermionic atoms confined in a potential created by standing wave light can undergo a phase transition to a superfluid state at a dramatically increased transition temperature. Depending upon carefully controlled parameters, ...
