Timing-injection locking in a self-starting Mamyshev oscillator induced by the dissipative Faraday instability

Posted by klaurent This Week: Astrophysics, Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Changqing Li, Ran Xia, Yutai Zhao, Yifang Li, Jia Liu | Summary: Mamyshev oscillators (MOs), a novel class of passively mode-locked fiber lasers, serve as an excellent platform to explore complex nonlinear dynamics, ranging from localized sturctures to chaos. Despite their versatility, achieving self-starting mode-locking remains a […]

Exponential quantum speedups in quantum chemistry with linear depth

Posted by klaurent Berkeley, This Week: Nanoscience

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Oskar Leimkuhler, K. Birgitta Whaley, , , | Summary: We prove classical simulation hardness, under the generalized $mathsf{P}neqmathsf{NP}$ conjecture, for quantum circuit families with applications in near-term quantum chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state […]
