We present a quantum algorithm for simulating the wave equation under Dirichlet and Neumann boundary conditions. The algorithm uses Hamiltonian simulation and quantum linear system algorithms as subroutines. It relies on factorizations of d...
Laser-free trapped-ion entangling gates with simultaneous insensitivity to qubit and motional decoherence [0.03%]
无需激光的离子囚禁系统中的纠缠门以及该系统对量子比特和运动退相干的同时不灵敏性

The dominant error sources for state-of-the-art laser-free trapped-ion entangling gates are decoherence of the qubit state and the ion motion. The effect of these decoherence mechanisms can be suppressed with additional control fields or wi...

We investigate the subradiance properties of n ⩾ 2 multilevel fermionic atoms loaded into the lowest motional level of a single trap (e.g., a single optical lattice site or an optical tweezer). As pointed out in our previous work [A...

We consider the Zeeman shift in Rydberg atoms induced by room-temperature blackbody radiation (BBR). BBR shifts to the Rydberg levels are dominated by the familiar BBR Stark shift. However, the BBR Stark shift and the BBR Zeeman shift exhib...
Separation estimation of two freely rotating dipole emitters near the quantum limit [0.03%]

According to Rayleigh's criterion, two incoherent emitters with a separation below the diffraction limit are not resolvable with a conventional fluorescence microscope. One method of superresolution microscopy (SRM) circumvents the diffract...

We theoretically investigate the effect of "glancing" collisions on the ultra-high vacuum (UHV) pressure readings of the cold atom vacuum standard (CAVS), based on either ultracold 7Li or 87Rb atoms. Here, glancing collisions are those coll...
Dielectronic resonances of [Formula: see text] and [Formula: see text] series in highly charged [Formula: see text] -shell tungsten ions [0.03%]

We present spectroscopic measurements and detailed theoretical analysis of inner-shell L M n and L N n ( n ⩾ 4 ) dielectronic resonances in highly charged M -shell ions of tungsten. The x-ray emission from W 49 + through W 64 ...
Joint Quantum-State and Measurement Tomography with Incomplete Measurements [0.03%]

Estimation of quantum states and measurements is crucial for the implementation of quantum information protocols. The standard method for each is quantum tomography. However, quantum tomography suffers from systematic errors caused by imper...

A Bose-Einstein condensate (BEC) is a quantum phase of matter achieved at low temperatures. Photons, one of the most prominent species of bosons, do not typically condense due to the lack of a particle number conservation. We recently descr...
Proposed experiment to measure nonlinear optical susceptibilities in the saturated regime [0.03%]

When an optical beam passes through a thin slice of a homogeneous material, the change of its phase and amplitude is characterized by the material's linear and nonlinear susceptibility, the latter also known as the hyperpolarizability. The ...
