Indistinguishability obfuscation, range avoidance, and bounded arithmetic

R Ilango, J Li, RR Williams - Proceedings of the 55th Annual ACM …, 2023 - dl.acm.org
The range avoidance problem (denoted by Avoid) asks to find a string outside of the range
of a given circuit C:{0, 1} n→{0, 1} m, where m> n. Although at least half of the strings of …

Cryptographic characterization of quantum advantage

T Morimae, Y Shirakawa, T Yamakawa - arXiv preprint arXiv:2410.00499, 2024 - arxiv.org
Quantum computational advantage refers to an existence of computational tasks that are
easy for quantum computing but hard for classical one. Unconditionally showing quantum …

Fourier Growth of Communication Protocols for XOR Functions

U Girish, M Sinha, A Tal, K Wu - 2023 IEEE 64th Annual …, 2023 - ieeexplore.ieee.org
The level-k 1-Fourier weight of a Boolean function refers to the sum of absolute values of its
level-k Fourier coefficients. Fourier growth refers to the growth of these weights as k grows. It …

Limitations of measure-first protocols in quantum machine learning

C Gyurik, R Molteni, V Dunjko - arXiv preprint arXiv:2311.12618, 2023 - arxiv.org
In recent works, much progress has been made with regards to so-called randomized
measurement strategies, which include the famous methods of classical shadows and …

One Clean Qubit Suffices for Quantum Communication Advantage

S Arunachalam, U Girish, N Lifshitz - arXiv preprint arXiv:2310.02406, 2023 - arxiv.org
We study the one-clean-qubit model of quantum communication where one qubit is in a pure
state and all other qubits are maximally mixed. We demonstrate a partial function that has a …

Quantum Communication Advantage in TFNP

M Göös, T Gur, S Jain, J Li - arXiv preprint arXiv:2411.03296, 2024 - arxiv.org
We exhibit a total search problem whose communication complexity in the quantum SMP
(simultaneous message passing) model is exponentially smaller than in the classical two …

Are uncloneable proof and advice states strictly necessary?

R Chatterjee, S Kundu, S Podder - arXiv preprint arXiv:2410.11827, 2024 - arxiv.org
Yes, we show that they are. We initiate the study of languages that necessarily need
uncloneable quantum proofs and advice. We define strictly uncloneable versions of the …

On the power of geometrically-local classical and quantum circuits

K Bharti, R Jain - arXiv preprint arXiv:2310.01540, 2023 - arxiv.org
We show a relation, based on parallel repetition of the Magic Square game, that can be
solved, with probability exponentially close to $1 $(worst-case input), by $1 D $(uniform) …

BQP, meet NP: Search-to-decision reductions and approximate counting

S Gharibian, J Kamminga - arXiv preprint arXiv:2401.03943, 2024 - arxiv.org
What is the power of polynomial-time quantum computation with access to an NP oracle? In
this work, we focus on two fundamental tasks from the study of Boolean satisfiability (SAT) …

On Bounded Advice Classes

S Marshall, C Gyurik, V Dunjko - arXiv preprint arXiv:2405.18155, 2024 - arxiv.org
Advice classes in computational complexity have frequently been used to model real-world
scenarios encountered in cryptography, quantum computing and machine learning, where …
