Landauer’s principle is a thermodynamics concept also relevant in information theory, which states that erasing one bit of information from an information system results in the dissipation of at least a specific amount (i.e., kBTln2) […]
Q-CTRL, a provider of quantum infrastructure software, has announced the availability of its Fire Opal performance management software on Rigetti’s latest 84-qubit Ankaa-3 quantum computer, accessible via the Rigetti Quantum Cloud Services (QCS) platform. This […]
Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular momentum is conserved when a single photon is converted into a pair—validating a key principle of physics at the […]
Scientists from TU Delft (The Netherlands) have observed quantum spin currents in graphene for the first time without using magnetic fields. These currents are vital for spintronics, a faster and more energy-efficient alternative to electronics. […]
Quantum 9, 1783 (2025). https://doi.org/10.22331/q-2025-06-24-1783 In this study, we explore the information capacity of open quantum systems, focusing on the effective channels formed by the subsystem of random quantum circuits and quantum Hamiltonian evolution. By […]
Quantum 9, 1782 (2025). https://doi.org/10.22331/q-2025-06-24-1782 Stabilizer states, which are also known as the Clifford states, have been commonly utilized in quantum information, quantum error correction, and quantum circuit simulation due to their simple mathematical structure. […]
Quantum 9, 1781 (2025). https://doi.org/10.22331/q-2025-06-24-1781 The dynamics of a quantum-many body system subject to measurements is naturally described by an ensemble of quantum trajectories, which can feature measurement-induced phase transitions (MIPTs). This phenomenon cannot be […]
Quantum 9, 1780 (2025). https://doi.org/10.22331/q-2025-06-24-1780 Weak coin flipping is a cryptographic primitive in which two mutually distrustful parties generate a shared random bit to agree on a winner via remote communication. While a stand-alone secure […]
Quantum 9, 1779 (2025). https://doi.org/10.22331/q-2025-06-24-1779 Fault-tolerant architectures aim to reduce the noise of a quantum computation. Despite such architectures being well studied a detailed understanding of how noise is transformed in a fault-tolerant primitive such […]
Quantum 9, 1778 (2025). https://doi.org/10.22331/q-2025-06-24-1778 Fermionic Hamiltonians play a critical role in quantum chemistry, one of the most promising use cases for near-term quantum computers. However, since encoding nonlocal fermionic statistics using conventional qubits results […]
