The Pinnacle Architecture: Reducing the cost of breaking RSA-2048 to 100 000 physical qubits using quantum LDPC codes
The realisation of utility-scale quantum computing inextricably depends on the design of practical, low-overhead fault-tolerant architectures. We introduce the \textit{Pinnacle Architecture}, which uses quantum low-density parity check (QLDPC) codes to allow for universal, fault-tolerant quantum computation with a spacetime overhead significantly smaller than that of any competing architecture. With this architecture, we show that 2048-bit RSA integers can be factored with less than one hundred thousand physical qubits, given a physical error rate of $10^{-3}$, code cycle time of $1$ \textmu s and a reaction time of $10$ \textmu s. We thereby demonstrate the feasibility of utility-scale quantum computing with an order of magnitude fewer physical qubits than has previously been believed necessary.

#ShtetlOptimized headlines with a groundbreaking revelation: Quantum computers won't magically solve your Rubik's Cube while you nap! Meanwhile,
#HSBC introduces the latest "qombie" threat to humanity, and Scott Aaronson reminds us that amplifying is for volume, not quantum supremacy π©.

The QMA Singularity
A couple days ago, Freek Witteveen of CWI and I posted a paper to the arXiv called βLimits to black-box amplification in QMA.β Let me share the abstract: We study the limitations of blaβ¦

#ShtetlOptimized is the usual goto for current QC papers and goings on. Also the accidentally on purpose knocking down of widely held quantum hucksterisms that often obscure the notion that quantum computation actually matters...
