Quantum 8, 1406 (2024). https://doi.org/10.22331/q-2024-07-11-1406 In this paper we will attempt to answer the following question: what are the natural quantum subsystems which emerge out of a system’s dynamical laws? To answer this question we […]
Researchers have developed a new method to significantly enhance quantum technology performance by using the cross-correlation of two noise sources to extend coherence time, improve control fidelity, and increase sensitivity for high-frequency sensing. This innovative […]
The idea of time travel has dazzled sci-fi enthusiasts for years. Science tells us that traveling to the future is technically feasible, at least if you’re willing to go near the speed of light, but […]
Implementing a fault-tolerant quantum processor requires coupling qubits to generate entanglement. Superconducting qubits are a promising platform for quantum information processing, but scaling up to a full-scale quantum computer necessitates interconnecting many qubits with low […]
EDF, in partnership with Quandela, Alice & Bob, and CNRS, has embarked on a groundbreaking €6.1 million ($6.542M USD) project named “Energy Optimization of Quantum Circuits” (OECQ), supported with a grant of up to €4.5 million […]
Insider Brief Qubit Pharmaceuticals reduced the number of qubits needed to compute the properties of small molecules with its Hyperion-1 emulator, developed in partnership with Sorbonne University. The hybrid approach combining high-performance computing and quantum […]

In a study published in Nature, a research team has, for the first time, observed the antiferromagnetic phase transition within a large-scale quantum simulator of the fermionic Hubbard model (FHM). Click to rate this post! […]
Quantum 8, 1405 (2024). https://doi.org/10.22331/q-2024-07-10-1405 We propose an estimation procedure for $d$-dimensional unitary transformations. For $dgt2$, the unitary transformations close to the identity are estimated saturating the quantum Cramér-Rao bound. For $d=2$, the estimation of […]
Quantum 8, 1404 (2024). https://doi.org/10.22331/q-2024-07-10-1404 The classical embeddability problem asks whether a given stochastic matrix $T$, describing transition probabilities of a $d$-level system, can arise from the underlying homogeneous continuous-time Markov process. Here, we investigate […]
