This paper demonstrates that the magnitude and sign of the fermion-mediated Casimir interaction in mesoscopic rings can be controlled via the Aharonov-Bohm effect, enabling the implementation of non-Clifford SWAP gates between spatially separated spin qubits to reduce overhead in universal quantum computation.
This paper demonstrates that ballistic planar Josephson junctions enable a kinematic probe of Cooper pair momentum by steering Andreev bound states into an adjacent normal region at a phase-controlled angle that significantly exceeds conventional momentum scales, offering a distinct alternative to energy-shift-based detection methods.
This paper investigates terahertz field-driven second-order nonlinear transport phenomena in two-dimensional tellurene, demonstrating that gate-tunable dc currents arising from skew scattering, side jump, and Berry curvature dipole mechanisms scale quadratically with the electric field and are strongly enhanced at low temperatures and lower frequencies.
This paper demonstrates that a GaAs nanopost containing a single InAs quantum dot serves as an effective broadband photonic platform for probing the coherent ultrafast dynamics of exciton-biexciton systems using four-wave mixing microscopy.
This paper proposes superconducting singlet-triplet qubits based on parallel-aligned double quantum dots in Josephson junctions, which offer circuit QED control and all-to-all connectivity without requiring spin-orbit interaction, thereby expanding material options and reducing control overhead while providing linear protection against noise.
This paper demonstrates the first coherent control of a Majorana parity qubit by realizing coherent coupling between two-site minimal Kitaev chains, where the authors observe parity oscillations that align with theoretical predictions for partially protected Majorana zero modes.
This paper presents a complete characterization of intravalley and intervalley tunnel couplings, including their complex valley phases, in a silicon double quantum dot, demonstrating how these phases govern measurable energy gaps and fill a critical gap in understanding sample-wide variations of key physical parameters like spin-orbit coupling and valley-orbit mixing.
By utilizing atom manipulation to introduce unpaired electrons via three pentagon defects in truxene-based molecular graphenoids, researchers demonstrated that these topological defects can be engineered to form a collective high-spin quartet state (S=3/2) through ferromagnetic coupling, offering a new platform for designing magnetic spin chains and networks.
This study demonstrates that atomically precise magnetic nanographenes on a lead superconductor exhibit a tunable quantum phase transition between singlet and doublet states, driven by the interplay between delocalized graphene spins and Cooper pairs, thereby offering a promising platform for exploring Majorana bound states and other low-dimensional quantum phenomena.
This paper proposes a purely magnetic mechanism for high-harmonic spin pumping that operates independently of spin-orbit coupling by introducing a static magnetic order parameter perpendicular to a precessing magnetization, thereby enabling strong nonlinear spin transport through magnetic structure and dynamics alone.
