I am broadly interested in quantum computation. Recently, I have been most excited about understanding the interplay between quantum computation and cryptography. Previously, Ihave studied foundational questions about entanglement and quantum correlations, inspired bythe question of certifying quantum devices.
Short Bio: Before UW, I was a postdoctoral researcher at UC Berkeley and the Simons Institute, working with Umesh Vazirani. I obtained my PhD at Caltech, where I was fortunate to be advised by Thomas Vidick. In a previous life, I received a B.A. in Mathematics from the University of Oxford and a Master in Mathematics from the University of Cambridge.I co-foundedqBraid, a cloud-based platform for learning quantum computing and developing quantum algorithms.

News:
Congratulations to Er-Cheng on the Machtey Award for best student paper at FOCS 2025, for this work with Miryam Huang!
I'm thankful to Google for a 2025 Research Scholaraward in quantum computing.
Applications are open for the first cohort of our NSF-funded Quantum@UW REU summer program! Consider applying if you are an undergrad interested in experiencing research in quantum information (projects ranging from theory to experiments). Deadline is March 13.
I'm spending Fall quarter 2024 in Oxford, at the department of Computer Science.
I'm giving a lecture series at the 22nd Bellairs Crypto Workshop in Barbados (Mar 3-7 2024) titled "Random and pseudorandom quantum states: how to use them".
Er-Cheng Tang is the first PhD student to join my group. Welcome!
