Dear all, Please see below for a talk that may be of interest to the HQI community. Best, Clare ---------- Forwarded message --------- From: Sergiy Verstyuk <verstyuk@cmsa.fas.harvard.edu<mailto:verstyuk@cmsa.fas.harvard.edu>> Date: Fri, Feb 14, 2020 at 4:03 PM Subject: CMSA Colloquium, February 19: Peter Shor (MIT) To: Sergiy Verstyuk <verstyuk@cmsa.fas.harvard.edu<mailto:verstyuk@cmsa.fas.harvard.edu>> Speaker: Peter Shor (MIT) Time: February 19, Wednesday, 16:30-17:30 Location: CMSA building, 20 Garden Street, Room G10<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.google.com_… Title: Quantum Money from Lattices Abstract: Quantum money is a cryptographic protocol for quantum computers. A quantum money protocol consists of a quantum state which can be created (by the mint) and verified (by anybody with a quantum computer who knows what the "serial number" of the money is), but which cannot be duplicated, even by somebody with a copy of the quantum state who knows the verification protocol. Several previous proposals have been made for quantum money protocols. We will discuss the history of quantum money and give a protocol which cannot be broken unless lattice cryptosystems are insecure. ***Please distribute among your colleagues***
