Score the Update, Not the Token: Descent-Aligned Routing for Combinatorial LoRA Experts

Priya Nair, Lukas Brenner, Maya Lindqvist +5

Mixture-of-LoRA-experts methods raise the capacity of low-rank adaptation by routing each token to a few low-rank experts. Nearly all of them tie one input-side factor to one outpu…

Trading modes against energy

Lukas Brenner, Beatriz Dias, Robert Koenig

We ask how much energy is required to weakly simulate an -qubit quantum circuit (i.e., produce samples from its output distribution) by a unitary circuit in a hybrid qubit-oscil…

Qubit-oscillator-based gate implementations for approximate Gottesman-Kitaev-Preskill codes

Lukas Brenner, Beatriz Dias, Robert Koenig

We consider hybrid qubit-oscillator systems together with Gaussian, multi-qubit as well as qubit-controlled Gaussian unitaries. We propose implementations of logical gates for appr…

Composable logical gate error in approximate quantum error correction: reexamining gate implementations in Gottesman-Kitaev-Preskill codes

Lukas Brenner, Beatriz Dias, Robert Koenig

Quantifying the accuracy of logical gates is paramount in approximate error correction, where perfect implementations are often unachievable with the available set of physical oper…

Factoring an integer with three oscillators and a qubit

Lukas Brenner, Libor Caha, Xavier Coiteux-Roy +1

A common starting point of traditional quantum algorithm design is the notion of a universal quantum computer with a scalable number of qubits. This convenient abstraction mirrors…

The complexity of Gottesman-Kitaev-Preskill states

Lukas Brenner, Libor Caha, Xavier Coiteux-Roy +1

We initiate the study of state complexity for continuous-variable quantum systems. Concretely, we consider a setup with bosonic modes and auxiliary qubits, where available operatio…

Optimal wire cutting with classical communication

Lukas Brenner, Christophe Piveteau, David Sutter

Circuit knitting is the process of partitioning large quantum circuits into smaller subcircuits such that the result of the original circuits can be deduced by only running the sub…
