SpectrumQuant: Spectrum Alignment for LLM Quantization
Dwaipayan Haldar, Indranil Patra, Azhar Yousuf +1
Orthogonal transforms have emerged as an effective tool for low-bit quantization of large language models (LLMs), as they reshape activation distributions without changing the unde…
Optimal purification of a spin ensemble by quantum-algorithmic feedback
Daniel M. Jackson, Urs Haeusler, Leon Zaporski +7
Purifying a high-temperature ensemble of quantum particles towards a known state is a key requirement to exploit quantum many-body effects. An alternative to passive cooling, which…
Witnessing quantum correlations in a nuclear ensemble via an electron spin qubit
Dorian A. Gangloff, Leon Zaporski, Jonathan H. Bodey +8
A coherent ensemble of spins interfaced with a proxy qubit is an attractive platform to create many-body coherences and probe the regime of collective excitations. An electron spin…
Quantum sensing of a coherent single spin excitation in a nuclear ensemble
Daniel M. Jackson, Dorian A. Gangloff, Jonathan H. Bodey +6
The measurement of single quanta in a collection of coherently interacting objects is transformative in the investigations of emergent quantum phenomena. An isolated nuclear-spin e…
Optical spin locking of a solid-state qubit
J. H. Bodey, R. Stockill, E. V. Denning +7
Quantum control of solid-state spin qubits typically involves pulses in the microwave domain, drawing from the well-developed toolbox of magnetic resonance spectroscopy. Driving a…
Quantum Interface of an Electron and a Nuclear Ensemble
Dorian Gangloff, Gabriel Éthier-Majcher, Constantin Lang +7
Coherent excitation of an ensemble of quantum objects underpins quantum many-body phenomena, and offers the opportunity to realize a quantum memory to store information from a qubi…
