The traditional distinction between tunnel and highly transmissive barriers does not currently
hold for high critical temperature superconducting Josephson junctions, both because of …

Thermal non-classical correlations quantified by concurrence entanglement, local quantum
uncertainty, and quantum coherence in a four-qubit square chain are exactly examined. The …

The recent growing interest in terahertz (THz) and sub-THz science and technology is due to
its many important applications in physics, astronomy, chemistry, biology and medicine …

For four decades semiconductor electronics has followed Moore's law: with each generation
of integration the circuit features became smaller, more complex and faster. This …

Several recent experiments revealed a change of the sign of the first harmonic in the current-
phase relation of Josephson junctions (JJs) based on, eg, d-wave superconductors or JJs …

Superconducting proximity effects in graphene have received a great deal of attention for
over a decade now. This has unveiled a plethora of exotic effects linked to the specificities of …

While Josephson–junction-like structures intrinsic to the layered cuprate high temperature
superconductors offer an attractive stage for exploiting possible applications to new …

Here we present the direct observation of macroscopic quantum properties in an all high-
critical-temperature superconductor d-wave Josephson junction. Although dissipation …

We have used Bi 2 Se 3 nanoribbons, grown by catalyst-free physical vapor deposition to
fabricate high quality Josephson junctions with Al superconducting electrodes. In our …

We have investigated macroscopic quantum tunneling in Bi 2 Sr 2 CaCu 2 O 8+ δ intrinsic
Josephson junctions at millikelvin temperatures using microwave irradiation. Measurements …
