Is quantum computing a threat to cryptography, and what can computer scientists and engineers do to prepare for this potential reality, and protect blockchains in a post-quantum world? a16z crypto Research Partner Lera Nikolaenko looks far into the future at how the world of computing could change when governed by new laws of physics. This talk examines the different kinds of quantum adversaries lurking in the future, tracks the progress toward general-purpose quantum computers, and shares new, quantum-safe cryptography that is being developed and deployed in response.
