Quantum 7, 1053 (2023). https://doi.org/10.22331/q-2023-07-11-1053 Extracting tomographic information about quantum states is a crucial task in the quest towards devising high-precision quantum devices. Current schemes typically require measurement devices for tomography that are a priori […]
Quantum 7, 1052 (2023). https://doi.org/10.22331/q-2023-07-11-1052 Banchi & Crooks (Quantum, 2021) have given methods to estimate derivatives of expectation values depending on a parameter that enters via what we call a “perturbed” quantum evolution $xmapsto e^{i(x […]
Quantum 7, 1051 (2023). https://doi.org/10.22331/q-2023-07-11-1051 In the recent years self-testing has grown into a rich and active area of study with applications ranging from practical verification of quantum devices to deep complexity theoretic results. Self-testing […]
Quantum 7, 1050 (2023). https://doi.org/10.22331/q-2023-07-11-1050 The topological charge $m$ of vortex electrons spans an infinite-dimensional Hilbert space. Selecting a two-dimensional subspace spanned by $m=pm 1$, a beam electron in a transmission electron microscope (TEM) can […]
Insider Brief Partnership will make Alice & Bob patented cat qubit technology accessible through QaptivaTM, Eviden’s quantum application development platform. Cat qubits are a promising approach to solving quantum computing’s biggest problem: computation errors, according […]
French quantum hardware startup Alice & Bob has announced it is partnering with Atos subsidiary Eviden to provide emulation capabilities of the Alice & Bob hardware on Eviden’s Qaptiva platform. This will allow end users […]
Josh Savory, product launch manager at Quantinuum, is interviewed by Yuval Boger. Josh and Yuval spoke about their recent H2 system launch,GHZ and non-abelian topological states, what the H2 launch means for customers, whether 32 […]
The quantum nature of interactions between elementary particles allows drawing non-trivial conclusions even from processes as simple as elastic scattering. The ATLAS experiment at the LHC accelerator reports the measurement of fundamental properties of strong […]
A team conducted an in-depth investigation of the magnetism of TbMn6Sn6, a Kagome layered topological magnet. They were surprised to find that the magnetic spin reorientation in TbMn6Sn6 occurs by generating increasing numbers of magnetically […]
Physicists at the University of Regensburg (UR) led by the research groups of Professor Dr. Christoph Strunk / Dr. Nicola Paradiso and Professor Dr. Jaroslav Fabian made an exciting discovery: In their publication just published […]
