- Majorana zero mode is a unique particle or bound state that belongs to the class of Majorana fermions.
- It was first proposed by the Italian physicist Ettore Majorana in 1937.
- Distinct characteristics: Majorana zero modes are bound states of particles that are their own antiparticles (counterpart particle with opposite quantum properties such as charge).
- This distinguishes Majorana zero modes from other particles in the quantum realm.
- Enhanced Stability:
- It provides increased stability for qubits, the fundamental units of information in quantum computing.
- Qubits: Just like bits (1 and 0) are the basic units by which computers process information, ‘qubits’ or ‘quantum bits’ are the units of process by quantum computers.
- A quantum computer stores information in the form of quantum bits (qubits) that can take on various combinations of zero and one.
- Even if one entity within the bound state is disturbed, the overall qubit remains protected and retains encoded information.
- Topological Quantum Computing:
- Majorana zero modes enable topological quantum computing, utilizing non-Abelian statistics.
- Non-Abelian statistics introduce an additional degree of freedom, allowing for different outcomes based on the order of computational steps.
- It provides enhanced stability for qubits in quantum computing.
