Design boosters: from constant-time quantum chaos to -designs and beyond
Soumik Ghosh, Arjun Mirani, Yihui Quek +1
We study a counterintuitive property of 'conditioning' on the result of measuring a subsystem of a quantum state: such conditioning can boost design quality, at the cost of increas…

Cryptographic tests of the python's lunch conjecture
Alex May, Sabrina Pasterski, Chris Waddell +1
In the AdS/CFT correspondence, a subregion of the CFT allows for the recovery of a corresponding subregion of the bulk known as its entanglement wedge. In some cases, an entangleme…

Efficient unitary designs and pseudorandom unitaries from permutations
Chi-Fang Chen, Adam Bouland, Fernando G. S. L. Brandão +3
In this work we give an efficient construction of unitary -designs using quantum gates, as well as an efficient construction of a parallel-secure pse…
