Fault-Tolerant Quantum Computation with Static Linear Optics

Simulating key properties of lithium-ion batteries with a fault-tolerant quantum computer

“…For a lower clock rate of 10 KHz, the runtime is a few years, even when using only n p = 4. On the other hand, assuming an optimistic but in principle achievable clock rate of 100 MHz [47,123], for n p = 4 we obtain a runtime estimate of less than an a day. For n p = 9, the runtime is a about a year.…”

“…These calculations depend on the hardware platform, and for this purpose we focus on photonic architectures such as those described in Refs. [47,123]. More specifically, we employ the formula in [ [47], Eq.…”

Protocol for Generating Optical Gottesman-Kitaev-Preskill States with Cavity QED

“…However, the method is fundamentally probabilistic and thus needs multiplexing to be scalable, which imposes a large resource overhead. Furthermore, it is unclear how efficient and noise tolerant the protocol is for generating highly squeezed GKP states (> 10 dB squeezing), which are likely required to achieve fault tolerance [6,7,25].…”
