Low depth amplitude estimation on a trapped ion quantum computer
Tudor Giurgica-Tiron, Sonika Johri, Iordanis Kerenidis +6
Amplitude estimation is a fundamental quantum algorithmic primitive that enables quantum computers to achieve quadratic speedups for a large class of statistical estimation problem…
Generative Quantum Learning of Joint Probability Distribution Functions
Elton Yechao Zhu, Sonika Johri, Dave Bacon +9
Modeling joint probability distributions is an important task in a wide variety of fields. One popular technique for this employs a family of multivariate distributions with unifor…
Detecting Qubit-coupling Faults in Ion-trap Quantum Computers
Andrii O. Maksymov, Jason Nguyen, Vandiver Chaplin +2
Ion-trap quantum computers offer a large number of possible qubit couplings, each of which requires individual calibration and can be misconfigured. To enhance the duty cycle of an…
Optimizing Electronic Structure Simulations on a Trapped-ion Quantum Computer using Problem Decomposition
Yukio Kawashima, Erika Lloyd, Marc P. Coons +12
Quantum computers have the potential to advance material design and drug discovery by performing costly electronic structure calculations. A critical aspect of this application req…
Generalized Hamiltonian to describe imperfections in ion-light interaction
Ming Li, Kenneth Wright, Neal C. Pisenti +3
We derive a general Hamiltonian that governs the interaction between an -ion chain and an externally controlled laser field, where the ion motion is quantized and the laser fiel…
Creation and Characterization of Matter-Wave Breathers
De Luo, Yi Jin, Jason H. V. Nguyen +6
We report the creation of quasi-1D excited matter-wave solitons, "breathers", by quenching the strength of the interactions in a Bose-Einstein condensate with attractive interactio…
Parametric Excitation of a Bose-Einstein Condensate: From Faraday Waves to Granulation
J. H. V. Nguyen, M. C. Tsatsos, D. Luo +4
We explore, both experimentally and theoretically, the response of an elongated Bose-Einstein condensate to modulated interactions. We identify two distinct regimes differing in mo…
Collisions of matter-wave solitons
Jason H. V. Nguyen, Paul Dyke, De Luo +2
Solitons are localised wave disturbances that propagate without changing shape, a result of a nonlinear interaction which compensates for wave packet dispersion. Individual soliton…
Broadband optical cooling of molecular rotors from room temperature to the ground state
Chien-Yu Lien, Christopher M. Seck, Yen-Wei Lin +3
Laser cycling of resonances can remove entropy from a system via spontaneously emitted photons, with electronic resonances providing the fastest cooling timescales because of their…
Prospects for Doppler cooling of three-electronic-level molecules
J. H. V. Nguyen, B. Odom
Analogous to the extension of laser cooling techniques from two-level to three-level atoms, Doppler cooling of molecules with an intermediate electronic state is considered. In par…
