About me

I would love to live in a world with large, error-corrected quantum computers. But right now we only have noisy, small ones. To illuminate paths or dead-ends towards that goal, much of my work involves applying information and complexity theory to open up new classical-quantum gaps, or study the limitations of near-term quantum devices. I strongly believe that scrutinizing theoretical physics through a computational lens will lead to its next paradigm shift.

Short bio:

2025-now: Assistant Professor of Computer Science and Physics at EPFL

2022-2024: Postdoctoral triumvirate at FU Berlin, Harvard University and MIT, supported by the Harvard Quantum Initiative research fellowship and Alexander von Humboldt research fellowship, under the wonderful guidance of Aram Harrow, Peter Shor, Anurag Anshu, Susanne Yelin and Jens Eisert.

Jan '17-Jan '22: Ph.D from Stanford University (Supervisor: Tsachy Weissman)
Supported by the Stanford Q-FARM Fellowship, Stanford Graduate Fellowship and National University of Singapore (NUS) Overseas Graduate Scholarship.

Aug 12 - Jun 16: B.S. (Phi Beta Kappa) in Physics and Mathematics, MIT (Supervisor: Peter W. Shor)
Thanks to my senior thesis on quantum and super-quantum enhancements to capacities of interference channels, my Erdös number is 3!

News

[Nov 2025] I am fortunate to have had three papers accepted as contributed talks to QIP 2026: Hamiltonian Decoded Quantum Interferometry, Information-Computation gaps in Quantum Learning via low-degree likelihood, and Learning Stabilizers with Noise, merged with its followup Average-Case Complexity of Quantum Stabilizer Decoding.
[Nov 2025] Our paper on non-unital noise has been accepted to Nature Physics.
[Oct 2025] I attended the KITP Program 'Learning the Fine Structure of Quantum Dynamics in Programmable Quantum Matter', where I led a discussion on pseudorandomness in condensed matter and gave an invited talk at the conference 'Frontiers of Programmable Quantum Dynamics: Advances and Applications'. I also gave invited talks at the EQUIPTNT Workshop in Munich, at Columbia University, at the IQIM Seminar at Caltech and at the QTech conference organized by the Hungarian Academy of Sciences.
[Oct 2025] I am delighted to serve on the QIP Program Committee for the third time!
[Oct 2025] Two new papers on the arXiv: Hamiltonian Decoded Quantum Interferometry and Quantum advantage from random geometrically-two-local Hamiltonian dynamics. The first paper is a generalization of the DQI algorithm to quantum (i.e. Hamiltonian) optimization problems and Gibbs Sampling; the second paper is a proposal for quantum advantage via running Hamiltonian time dynamics for constant time.
[July 2025] I gave a talk at WERQSHOP, the Workshop on Error Resilience in Quantum computing, organized by the Unitary Foundation. This meaningful workshop brought together academics with industry practitioners to really hash out the challenges in quantum error mitigation and error-resilient compilation. The findings from this workshop have been summarized into a report.
[Jun 2025] Our paper, Information-Computation gaps in Quantum Learning via low-degree likelihood, is on arXiv. Thanks to Sitan Chen, Weiyuan Gong and Jonas Haferkamp for a great collaboration.
[Mar 2025] I gave invited talks on pseudochaos at the Stanford Institute for Theoretical Physics Seminar, the Simons Institute Quantum Pod and the MIT QI group meeting.
[Apr 2025] Our paper, Simulating quantum chaos without chaos, has been selected as a contributed talk at TQC 2025.
[Jan 2025] Our paper, Learning quantum states and Unitaries of bounded gate complexity, has been featured on the cover of PRX Quantum!
