Quantum state preparation, tomography, and entanglement of mechanical oscillators
E. Alex Wollack, Agnetta Y. Cleland, Rachel G. Gruenke +3
Precisely engineered mechanical oscillators keep time, filter signals, and sense motion, making them an indispensable part of today's technological landscape. These unique capabili…
Mirror symmetric on-chip frequency circulation of light
Jason F. Herrmann, Vahid Ansari, Jiahui Wang +3
Integrated circulators and isolators are important for developing on-chip optical technologies, such as laser cavities, communication systems, and quantum information processors. T…
High efficiency second harmonic generation of blue light on thin film lithium niobate
Taewon Park, Hubert S. Stokowski, Vahid Ansari +4
We demonstrate second harmonic generation of blue light on an integrated thin-film lithium niobate waveguide and observe a conversion efficiency of , si…
Automated discovery of autonomous quantum error correction schemes
Zhaoyou Wang, Taha Rajabzadeh, Nathan Lee +1
We can encode a qubit in the energy levels of a quantum system. Relaxation and other dissipation processes lead to decay of the fidelity of this stored information. Is it possible…
Longitudinal piezoelectric resonant photoelastic modulator for efficient intensity modulation at megahertz frequencies
Okan Atalar, Raphaël Van Laer, Amir H. Safavi-Naeini +1
Intensity modulators are an essential component in optics for controlling free-space beams. Many applications require the intensity of a free-space beam to be modulated at a single…
Photonic modal circulator using temporal refractive-index modulation with spatial inversion symmetry
Jiahui Wang, Jason F. Herrmann, Jeremy D. Witmer +2
It has been demonstrated that dynamic refractive index modulation, which breaks time-reversal symmetry, can be used to create on-chip non-reciprocal photonic devices. In order to a…
