Universality of Rényi Entropy in Conformal Field Theory

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Yuya Kusuki, Hirosi Ooguri, Sridip Pal, , | Summary: We use the thermal effective theory to prove that, for the vacuum state in any conformal field theory in $d$ dimensions, the $n$-th R’enyi entropy $S_A^{(n)}$ behaves as $S_A^{(n)} = frac{f}{(2pi n)^{d-1}} frac{ {rm Area}(partial A)}{(d-2)epsilon^{d-2}}left(1+O(n)right)$ in the […]

Exchange cross-talk mitigation in dense quantum dot arrays

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Daniel Jirovec, Pablo Cova Fariña, Stefano Reale, Stefan D. Oosterhout, Xin Zhang | Summary: Coupled spins in semiconductor quantum dots are a versatile platform for quantum computing and simulations of complex many-body phenomena. However, on the path of scale-up, cross-talk from densely packed electrodes poses a severe […]

StrokeFusion: Vector Sketch Generation via Joint Stroke-UDF Encoding and Latent Sequence Diffusion

Kavli Affiliate: Yi Zhou | First 5 Authors: Jin Zhou, Yi Zhou, Pengfei Xu, Hui Huang, | Summary: In the field of sketch generation, raster-format trained models often produce non-stroke artifacts, while vector-format trained models typically lack a holistic understanding of sketches, leading to compromised recognizability. Moreover, existing methods struggle to extract common features from […]

Exponential quantum speedups in quantum chemistry with linear depth

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Oskar Leimkuhler, K. Birgitta Whaley, , , | Summary: We prove classical simulation hardness, under the generalized $mathsf{P}neqmathsf{NP}$ conjecture, for quantum circuit families with applications in near-term chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state inputs, […]
