We show that parametric coupling techniques can be used to generate selective entangling interactions for multi-qubit processors. By inducing coherent population exchange between adjacent qubits under frequency modulation, we implement a universal gate set for a linear array of four superconducting qubits. An average process fidelity of ℱ = 93% is estimated for three two-qubit gates via quantum...
This paper describes a new method of retroactively programming a genetic circuit to exhibit the behavior of one of four logic gates (AND, OR, NAND, and NOR) using pulses of light. These pulses must occur after DNA transfection into the host cell. The pulses of light deactivate a photosensitive kinase, inhibiting phosphorylation. Using this effect, we can control the transcription of recombinase...
A generic way to design lightweight cryptographic primitives is to construct simple rounds using small nonlinear components such as 4x4 S-boxes and use these iteratively (e.g., PRESENT [1] and SPONGENT [2]). In order to efficiently implement the primitive, efficient implementations of its internal components are needed. Multiplicative complexity of a function is the minimum number of AND gates ...
Constant-depth polynomial-size threshold circuits are usually classi ed according to their total depth. For example, the best known threshold circuits for iterated multiplication and division have depth four and three, respectively. In this paper, the complexity of threshold circuits is investigated from a di erent point of view: explicit AND, OR gates are allowed in the circuits, and a thresho...
Many semiconductor quantum devices utilize a novel tunneling transport mechanism that allows picosecond device switching speeds. The negative differential resistance characteristic of these devices, achieved due to resonant tunneling, is also ideally suited for the design of highly compact, self-latching logic circuits. As a result, quantum device technology is a promising emerging alternative ...
We study level mixing in the single particle energy spectrum of one of the constituent quantum dots in a vertical double quantum dot by performing magneto-resonant-tunneling spectroscopy. The device used in this study differs from previous vertical double quantum dot devices in that the single side gate is now split into four separate gates. Because of the presence of natural perturbations caus...
DNA strand displacement has been widely used for the design of molecular circuits, motors, and sensors in cell-free settings. Recently, it has been shown that this technology can also operate in biological environments, but capabilities remain limited. Here, we look to adapt strand displacement and exchange reactions to mammalian cells and report DNA circuitry that can directly interact with a ...
This contribution describes a comprehensive comparison of bit parallel nite eld multipliers. Four diierent multipliers in standard, dual, and normal base together with a relatively new approach which uses composite elds are compared. Four diierent eld orders from 2 8 to 2 32 are investigated. A high practical relevance is assured by using a highly automated design process and sea-of-gates chip ...
Gates are a new notation for representing mixture models and context-sensitive independence in factor graphs. Factor graphs provide a natural representation for message-passing algorithms, such as expectation propagation. However, message passing in mixture models is not well captured by factor graphs unless the entire mixture is represented by one factor, because the message equations have a c...
The electrical properties and rectification behavior of the graphene self-switching diodes by side gates doping with nitrogen and boron atoms were investigated using density functional tight-binding method. The devices gates doping changes the electrical conductivity of the side gates and the semiconductor channel nanoribbons. As a result, the threshold voltage value under the forward bias is s...
