Photonic QPU With Coherent States for Reversible Quantum Logic

Annalen der Physik, Volume 538, Issue 2, February 2026.
A photonic Quantum Processing Unit X (QPU X) design leveraging coherent‐state qubits and linear optics probabilistically implements fundamental logical gates‐including AND, OR, C‐NOT, C¯$\bar{C}$‐NOT, Toffoli (C2${\rm C}^2$‐NOT), and Fredkin (C‐SWAP)‐with success probabilities up to 1/4 for simpler gates.

Strain Effects in a Directly Bonded Diamond‐on‐Insulator Substrate

physica status solidi (a), Volume 223, Issue 3, February 2026.
Strain effects in a directly bonded diamond‐on‐insulator substrate are investigated using NV‐based optically detected magnetic resonance and photoluminescence mapping. Enhanced volumetric and shear strain is observed near the bonded interface, but without significant degradation of NV optical properties.

Rigidifying Qubit Candidates in a Cu‐Porphyrin Nanohoop: Dipolar Coupling in Spin Pairs and Spin‐Polarized Ground State

Angewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.
A conjugated nanohoop, Cu[3]CPTA, containing three Cu(II) porphyrin spin centers (S = ½) was synthesized. We show that the exceptionally high “nanohoop rigidity” results in well‐defined dipolar coupling (DEER) and a rare light‐induced spin polarization of the doublet ground state in frozen solution (transient cwEPR).

Bound on the distance between controlled quantum state and target state under decoherence

Journal of Physics Communications
To implement quantum information technologies, carefully designed control for preparing a desired state plays a key role. However, in realistic situation, the actual performance of those methodologies is severely limited by decoherence.
