Kasner Exponents from the Bouncing Singularity

Thermal two-point functions of holographic CFTs can probe the black hole singularity. When a bouncing geodesic exists, the correlator at leading order in $1/N$ develops a singularity $G(t, \vec{x}=0) \propto (t_c-t)^{-2\Delta+b_t}$, where $\Delta$ is the scaling dimension of the operator. We show that the additional ex...

Signal-to-noise problems in fault-tolerant quantum computation

Quantum computation offers a promising alternative to classical Monte Carlo methods by naturally avoiding sign problems through unitary evolution. A common misconception follows from this: because quantum simulation sidesteps the sign problem, it is often assumed to be an essentially perfect substitute for classical sa...
