Efficient Unclonable Encryption from Pauli Eigenstates
Seyoon Ragavan
We give, to our knowledge, the first plain-model, one-time information-theoretically secure, efficient unclonable encryption scheme for one classical bit. Previous work by Bhattach…
Optimization Using Locally-Quantum Decoders
Noah Shutty, Avijit Mandal, Seyoon Ragavan +8
It was pointed out in [JSW+25] that widely-studied optimization problems such as D-regular max-k-XORSAT can be reduced to decoding of LDPC codes, using quantum algorithms related t…
Parallel Spooky Pebbling Makes Regev Factoring More Practical
Gregory D. Kahanamoku-Meyer, Seyoon Ragavan, Katherine Van Kirk
Pebble games, an abstraction from classical reversible computing, have found use in the design of quantum circuits for inherently sequential tasks. Gidney showed that allowing Hada…
The Jacobi Factoring Circuit: Quantum Factoring with Near-Linear Gates and Sublinear Space and Depth
Gregory D. Kahanamoku-Meyer, Seyoon Ragavan, Vinod Vaikuntanathan +1
We present a compact quantum circuit for factoring a large class of integers, including some whose classical hardness is expected to be equivalent to RSA (but not including RSA int…
Cloning Games, Black Holes and Cryptography
Alexander Poremba, Seyoon Ragavan, Vinod Vaikuntanathan
In this work, we introduce a new toolkit for analyzing cloning games, a notion that captures stronger and more quantitative versions of the celebrated quantum no-cloning theorem. T…
