Rabi splitting and optical Kerr nonlinearity of quantum dot mediated by Majorana fermions

Viewing Majorana Bound States by Rabi Oscillations

We propose to use Rabi oscillation as a probe to view the fractional Josepshon relation (FJR) associated with Majorana bound states (MBSs) expected in one-dimensional topological superconductors. The system consists of a quantum dot (QD) and an rf-SQUID with MBSs at the Josephson junction. Rabi oscillations between energy levels formed by MBSs are induced by ac gate voltage controlling the coup...

Suppression of pulse splitting in two-core optical fibers with Kerr nonlinearity

Extracting entangled qubits from Majorana fermions in quantum dot chains through the measurement of parity

We propose a scheme for extracting entangled charge qubits from quantum-dot chains that support zero-energy edge modes. The edge mode is composed of Majorana fermions localized at the ends of each chain. The qubit, logically encoded in double quantum dots, can be manipulated through tunneling and pairing interactions between them. The detailed form of the entangled state depends on both the par...

Towards quantum computation with Majorana fermions

In 1937 the Italian physicist Ettore Majorana proposed the existence of a massless, chargeless, spinless particle that is its own antiparticle. Such a Majorana fermion would have an extraordinarily large phase coherence time, making it an ideal building block for a quantum computer. However, no Majorana fermions are known to exist asfundamental particles. The recent discovery of topological sta...
