The Entire Quantum Computer on a Classical Leash
Yael Tauman Kalai, Dakshita Khurana, Justin Raizes
We show that a classical client with no quantum hardware can use a single untrusted and potentially malicious quantum server as if it were its own trusted quantum computer. Through…
Query-Limited RAM Programs and their Applications
Jiahui Liu, Justin Raizes, Bhaskar Roberts +1
Quantum one-time programs (Broadbent, Gutoski and Stebila, CRYPTO 2013) or OTPs for short, enable a functionality to be encoded into a quantum token that can be evaluated on a sing…
Semi-Quantum Cryptography with Certified Deletion
Yael Tauman Kalai, Justin Raizes
Certified deletion allows a client to upload encrypted data to a server as a quantum state, then later request that the server delete their data and detect whether the server compl…
On Best-Possible One-Time Programs
Aparna Gupte, Jiahui Liu, Luowen Qian +3
One-time programs (OTPs) aim to let a user evaluate a program on a single input while revealing nothing else. Classical OTPs require hardware. Quantum measurement suggests a physic…
How to Classically Verify a Quantum Cat without Killing It
Yael Tauman Kalai, Dakshita Khurana, Justin Raizes
A quantum verifier decides membership in QMA using a (single) quantum witness state. This witness may be arbitrary, and no requirement is placed on it beyond its acceptance probabi…
