Security of quantum bit string commitment depends on the information measure
Harry Buhrman, Matthias Christandl, Patrick Hayden +2
Unconditionally secure non-relativistic bit commitment is known to be impossible in both the classical and the quantum world. However, when committing to a string of n bits at once…

New Limits on Fault-Tolerant Quantum Computation
Harry Buhrman, Richard Cleve, Monique Laurent +3
We show that quantum circuits cannot be made fault-tolerant against a depolarizing noise level of approximately 45%, thereby improving on a previous bound of 50% (due to Razborov).…
