In this paper, a new voltage controlled first order all-pass filter is presented. The proposed circuit employs a single differential voltage dual-X second generation current conveyor (DV-DXCCII) and a grounded capacitor only. The proposed all-pass filter provides both inverting and non inverting voltage-mode outputs from the same configuration simultaneously without any matching condition. Non-...

We show how to construct a fast quantum circuit for computing the sum of two n-bit binary numbers with few qubits. The constructed circuit uses O(n/ logn) ancillary qubits and its depth and size are O(logn) and O(n), respectively. The number of ancillary qubits is asymptotically less than that in Draper et al.’s quantum carry-lookahead adder, and the depth and size are asymptotically the same a...

In this lecture, we will talk about circuit lower bound for constant-depth circuit with MODp gates. Using switching lemma, we can prove exponential size lower bound for constant-depth circuit computing parity and majority. What if parity (=MOD2 gates) are allowed? It was conjectured that majority still needs exponential size to compute in constant-depth circuit. Razborov (1987) solves this conj...

Unlike fixed designs, programmable circuit designs support an infinite number of operators. The functionality of a programmable circuit can be altered by simply changing the angle values of the rotation gates in the circuit. Here, we present a new quantum circuit design technique resulting in two general programmable circuit schemes. The circuit schemes can be used to simulate any given operato...

Unsupervised training of generative models is a machine learning task that has many applications in scientific computing. In this work we evaluate the efficacy using quantum circuit-based to generate synthetic data high energy physics processes. We use non-adversarial, gradient-based circuit Born machines joint distributions over 2 and 3 variables.

A lattice surgery protocol is introduced to optimize quantum computing, helping eliminate extra circuit components and gate scheduling complexities, or reduce runtimes the total space-time costs.

Reconfigurable computing is a computer architecture which is intended to fill the gap between the hardware and the software, achieving potentially much higher performance than software, while maintaining a higher level of flexibility than hardware. Most commonly and widely used high speed computing fabrics deployed in reconfigurable computing are field-programmable gate arrays (FPGAs). This pap...
