A fault-tolerant non-Clifford gate for the surface code in two dimensions [PDF]
Sci. Adv. 6, eaay4929 (2020), 2019 Fault-tolerant logic gates will consume a large proportion of the resources of a two-dimensional quantum computing architecture. Here we show how to perform a fault-tolerant non-Clifford gate with the surface code; a quantum error-correcting code now under intensive development. This alleviates the need for distillation or higher-dimensional components

Fast universal two-qubit gate for neutral fermionic atoms in optical tweezers [PDF]
Phys. Rev. Research 3, 013113 (2021), 2020 An array of ultracold neutral atoms held in optical micro-traps is a promising platform for quantum computation. One of the major bottlenecks of this platform is the weak coupling strength between adjacent atoms, which limits the speed of two-qubit gates.

True Random Number Generator Based on Fibonacci-Galois Ring Oscillators for FPGA
Applied Sciences, 2021 Random numbers are widely employed in cryptography and security applications. If the generation process is weak, the whole chain of security can be compromised: these weaknesses could be exploited by an attacker to retrieve the information, breaking even

Scaling Ion Trap Quantum Computation through Fast Quantum Gates [PDF]
Phys. Rev. Lett. 93, 100502 (2004)., 2004 We propose a method to achieve scalable quantum computation based on fast quantum gates on an array of trapped ions, without the requirement of ion shuttling. Conditional quantum gates are obtained for any neighboring ions through spin-dependent acceleration of the ions from periodic photon kicks.

Theory of a field effect transistor based on semiconductor nanocrystal array [PDF]
Phys. Rev. B 89, 235303 (2014), 2014 We study the surface conductivity of a field-effect transistor (FET) made of periodic array of spherical semiconductor nanocrystals (NCs). We show that electrons introduced to NCs by the gate voltage occupy one or two layers of the array. Computer simulations and analytical theory are used to study the array screening and corresponding evolution of ...

Random background charges and Coulomb blockade in one-dimensional tunnel junction arrays [PDF]
Phys. Rev. B 63, 014201 (2001), 2000 We have numerically studied the behavior of one dimensional tunnel junction arrays when random background charges are included using the ``orthodox'' theory of single electron tunneling. Random background charge distributions are verified in both amplitude and density. The use of a uniform array as a transistor is discussed both with and without random
