Reversible computation plays an important role in the synthesis of circuits having application in quantum computing, low power CMOS design, bioinformatics and nanotechnology-based systems. Conventional logic circuits are not reversible. A reversible circuit maps each input vector, into a unique output vector and vice versa. We demonstrate how the well-known and very useful, Toffoli gate can be ...

Quantum error correction allows one to make quantum computers fault-tolerant against unavoidable errors due to decoherence and imperfect physical gate operations. However, the fault-tolerant quantum computation requires impractically large computational resources for useful applications. This is a current major obstacle to the realization of a quantum computer. In particular, magic state distil...

We propose a two-qubit collisional phase gate that can be implemented with available atom chip technology, and present a detailed theoretical analysis of its performance. The gate is based on earlier phase gate schemes, but uses a qubit state pair with an experimentally demonstrated, very long coherence lifetime. Microwave near-fields play a key role in our implementation as a means to realize ...

R.ADITHYA ABSTRACT In this paper an ultra low power and probabilistic based noise tolerant latch is proposed based on Markov Random Field (MRF) theory. The absorption laws and H tree logic combination techniques are used to reduce the circuit complexity of MRF noise tolerant latch. The cross coupled latching mechanism is used at the output of the MRF latch inorder to preserve the noise tolerant...

One of the key areas in which evolvable hardware has shown to excel is in achieving robust analogue and digital electronics. In this paper this domain is investigated further by manipulation of the digital abstraction. Some of the strict requirements of digital gates are relaxed in order to increase the complexity of the functionality available to evolution in order to evolve fault tolerant des...

—Reversible logic design has become one of the promising research directions in low power dissipating circuit design in the past few years and has found its application in low power CMOS design, digital signal processing and nanotechnology. This paper presents the efficient design approaches of fault tolerant carry skip adders (FTCSAs) and compares those designs with the existing ones. Variable...

We consider realistic, multiparameter error models and investigate the performance of the surface code for three possible fault-tolerant superconducting quantum computer architectures. We map amplitude and phase damping to a diagonal Pauli “depolarization” channel via the Pauli twirl approximation, and obtain the logical error rate as a function of the qubit T1,2 and state preparation, gate, an...
