A Quantum Bluestein's Algorithm for Arbitrary-Size Quantum Fourier Transform

Nan-Hong Kuo, Renata Wong·Dec 17, 2025

We propose a quantum analogue of Bluestein's algorithm (QBA) that implements an exact $N$-point Quantum Fourier Transform (QFT) for arbitrary $N$. Our construction factors the $N$-dimensional QFT unitary into three diagonal quadratic-phase gates and ...

Improved Lower Bounds for QAC0

Malvika Raj Joshi, Avishay Tal, Francisca Vasconcelos +1 more·Dec 16, 2025

In this work, we prove the strongest known lower bounds for QAC$^0$, allowing polynomially many gates and ancillae. Our main results show that: (1) Depth-3 QAC$^0$ circuits cannot compute PARITY, and require $Ω(\exp(\sqrt{n}))$ gates to compute MAJOR...

Hybrid acousto-optical spin control in quantum dots

Mateusz Kuniej, Paweł Machnikowski, Michał Gawełczyk·Dec 16, 2025

Mechanical degrees of freedom very weakly couple to spins in semiconductors. The inefficient coupling between phonons and single electron spins in semiconductor quantum dots (QDs) hinders their integration into on-chip acoustically coupled quantum hy...
