Requirement for quantum computation

چکیده
We identify “proper quantum computation” with computational processes that cannot be efficiently simulated on a classical computer. For optical quantum computation, we establish “no-go” theorems for classes of quantum optical experiments that cannot yield proper quantum computation, and we identify requirements for optical proper quantum computation that correspond to violations of assumptions underpinning the

Theoretical computation of the quantum transport of zigzag mono-layer Graphenes with various z-direction widths
The quantum transport computations have been carried on four different width of zigzag graphene using a nonequilibrium Green’s function method combined with density functional theory. The computed properties are included transmittance spectrum, electrical current and quantum conductance at the 0.3V as bias voltage. The considered systems were composed from one-layer graphene sheets differing w...

متن کاملA novel vedic divider based crypto-hardware for nanocomputing paradigm: An extended perspective
Restoring and non-restoring divider has become widely applicability in the era of digital computing application due to its computation speed. In this paper, we have proposed the design of divider of different architecture for the computation of Vedic sutra based. The design of divider in the Vedic mode results in high computation throughput due to its replica architecture, where latency is mini...

متن کاملScalable Quantum Networks Based on Few-qubit Registers
We describe and analyze a hybrid approach to scalable quantum computation based on an optically connected network of few-qubit quantum registers. We show that probabilistically connected ̄ve-qubit quantum registers su±ce for deterministic, fault-tolerant quantum computation even when state preparation, measurement, and entanglement generation all have substantial errors. We discuss requirements ...
