Brain implants have improved dramatically in recent years, but they’re still invasive and unreliable. A new kind of brain-machine interface using living neurons to form connections could be the future. While companies like Neuralink have […]

Quantum 8, 1573 (2024). https://doi.org/10.22331/q-2024-12-18-1573 We introduce Port-Based State Preparation (PBSP), a teleportation task where Alice holds a complete classical description of the target state and Bob’s correction operations are restricted to only tracing out […]
Quantum 8, 1572 (2024). https://doi.org/10.22331/q-2024-12-18-1572 Non-destructive heralded entanglement with photons is a valuable resource for quantum information processing. However, they generally entail ancillary particles and modes that amplify the circuit intricacy. To address this challenge, […]
Quantum 8, 1571 (2024). https://doi.org/10.22331/q-2024-12-18-1571 Optimized quantum control can enhance the performance and noise resilience of quantum metrology. However, the optimization quickly becomes intractable when multiple control operations are applied sequentially. In this work, we […]
Quantum 8, 1570 (2024). https://doi.org/10.22331/q-2024-12-17-1570 The popular qubit framework has dominated recent work on quantum kernel machine learning, with results characterising expressivity, learnability and generalisation. As yet, there is no comparative framework to understand these […]
Quantum 8, 1569 (2024). https://doi.org/10.22331/q-2024-12-17-1569 As quantum processors advance, the emergence of large-scale decentralized systems involving interacting quantum-enabled agents is on the horizon. Recent research efforts have explored quantum versions of Nash and correlated equilibria […]
Quantum 8, 1568 (2024). https://doi.org/10.22331/q-2024-12-17-1568 We explore the cryptographic power of arbitrary shared physical resources. The most general such resource is access to a fresh entangled quantum state at the outset of each protocol execution. […]
Quantum 8, 1567 (2024). https://doi.org/10.22331/q-2024-12-17-1567 Hamiltonian simulation is arguably the most fundamental application of quantum computers. The Magnus operator is a popular method for time-dependent Hamiltonian simulation in computational mathematics, yet its usage requires the […]
Quantum 8, 1566 (2024). https://doi.org/10.22331/q-2024-12-17-1566 Bosonic systems with negative Wigner function superposition states are fundamentally witnessing nonlinear quantum dynamics beyond linearized systems and, recently, have become essential resources of quantum technology with many applications. Typically, […]
Quantum 8, 1565 (2024). https://doi.org/10.22331/q-2024-12-16-1565 We study the back-reaction of quantum systems onto classical ones. Taking the starting point that semi-classical physics should be described at all times by a point in classical phase space […]
