The complexity of quantum support vector machines
Gian Florin Gentinetta, Stefan Woerner
Quantum support vector machines employ quantum circuits to define the kernel function. It has been shown that this approach offers a provable exponential speedup compared to any known classical algorithm for certain data sets. The training of such models c ...
Wien2024Dual-frame optimization for informationally complete quantum measurements
Randomized measurement protocols such as classical shadows represent powerful resources for quantum technologies, with applications ranging from quantum state characterization and process tomography to machine learning and error mitigation. Recently, the n ...
2024Variational quantum time evolution without the quantum geometric tensor
Giuseppe Carleo, Riccardo Rossi, Julien Sebastian Gacon, Jannes Willy E. Nys, Stefan Woerner
Realand imaginary -time quantum state evolutions are crucial in physics and chemistry for exploring quantum dynamics, preparing ground states, and computing thermodynamic observables. On near -term devices, variational quantum time evolution is a promising ...
College Pk2024Room-Temperature Quantum Optomechanics and Free-Electron Quantum Optics
Quantum optics studies how photons interact with other forms of matter, the understanding of which was crucial for the development of quantum mechanics as a whole. Starting from the photoelectric effect, the quantum property of light has led to the develop ...
EPFL2024Scalable Quantum Algorithms for Noisy Quantum Computers
Quantum computing not only holds the potential to solve long-standing problems in quantum physics, but also to offer speed-ups across a broad spectrum of other fields. Access to a computational space that incorporates quantum effects, such as superposition ...
EPFL2024A Comparative Analysis of Tools & Task Types for Measuring Computational Problem-Solving
Richard Lee Davis, Engin Walter Bumbacher, Jérôme Guillaume Brender
How to measure students' Computational Problem-Solving (CPS) competencies is an ongoing research topic. Prevalent approaches vary by measurement tools (e.g., interactive programming, multiple-choice tests, or programming-independent tests) and task types ( ...
Association for Computing Machinery2024Secure and Efficient Cryptographic Algorithms in a Quantum World
Since the advent of internet and mass communication, two public-key cryptographic algorithms have shared the monopoly of data encryption and authentication: Diffie-Hellman and RSA. However, in the last few years, progress made in quantum physics -- and mor ...
EPFL2024Emergence of highly coherent two-level systems in a noisy and dense quantum network
Sandrine Gerber, Gabriel Aeppli
Quantum sensors and qubits are usually two-level systems (TLS), the quantum analogues of classical bits assuming binary values 0 or 1. They are useful to the extent to which superpositions of 0 and 1 persist despite a noisy environment. The standard prescr ...
