Mahatma Gandhi Institute of Technology
'QUBIT' is the annual technical fest of the Department of Computer Science. It is a prestigious technological event in the state with papers presented from all over the country. It has risen beyond its technical reach and incorporated cultural aspects with the introduction of Lan-Gaming, Treasure Hunts, Fun Stalls etc. giving it an all round reach. It is organised during the month of March right from the year of its inception without fail. It is a technical symposium for young minds and meeting ground for tech-enthusiasts from around the country.
Superconducting quantum computing
Coupling qubits is essential for implementing 2-qubit gates. Coupling two qubits may be achieved by connecting them to an intermediate electrical coupling circuit. The circuit might be a fixed element, such as a capacitor, or controllable, such as a DC-SQUID. In the first case, decoupling the qubits (during the time the gate is off) is achieved by tuning the qubits out of resonance one from another, i.e. making the energy gaps between their computational states different. This approach is inherently limited to allow nearest-neighbor coupling only, as a physical electrical circuit is to be lay out in between the connected qubits. Notably, D-Wave Systems' nearest-neighbor coupling achieves a highly connected unit cell of 8 qubits in the Chimera graph configuration. Generally, quantum algorithms require coupling between arbitrary qubits, therefore the connectivity limitation is likely to require multiple swap operations, limiting the length of the possible quantum computation before the processor decoherence.
