Abstract:In this paper, the quantum mechanical (QM) effects in bulk MOSFETs and their modeling approaches in the compact modeling framework are reviewed. As the device dimensions are scaled to the sub-100 nm range, QM effects affect the device properties, such as effective oxide thickness, inversion layer charge density and profile, threshold voltage, effective bandgap, gate capacitance, mobility, surface potential, subthreshold characteristics, drain current, and gate leakage current. The classical theory is no longer… Show more
“…As we require three elements, 0, 1 and ⊥, we define 0 by 00, 1 by 11 and ⊥ by 01. Note that the dealer who will distribute the shares is honest and can compute the function described in Equation (1).…”

“…On the other hand, in quantum domain the adversary is always assumed to have unbounded power of computation and the security of a protocol comes from the laws of physics. This is why many researchers have tried to exploit the quantum mechanical effect [1] to solve the problems of SMC [2][3][4][5][6][7][8][9].…”

“…Different from classical counterpart, secure computation in the quantum mechanism can attain unconditional security because the security is ensured by some physical principles, such as the Heisenberg uncertainty principle and the quantum no-cloning theorem. Under this background, making use of quantum mechanical effect [4] to solve SMC problem has been attracting more and more attention.…”
As an important branch of quantum secure multiparty computation, quantum
private comparison (QPC) has attracted more and more attention recently. In
this paper, according to the quantum implementation mechanism that these
protocols used, we divide these protocols into three categories: The quantum
cryptography QPC, the superdense coding QPC, and the entanglement swapping QPC.
And then, a more in-depth analysis on the research progress, design idea, and
substantive characteristics of corresponding QPC categories is carried out,
respectively. Finally, the applications of QPC and quantum secure multi-party
computation issues are discussed and, in addition, three possible research
mainstream directions are pointed out
“…Gate tunneling current depends on the device structure and biasing conditions. At high electric field, tunneling of electrons take place from gate to bulk and also from bulk to gate region through the gate oxide layer (i.e the quantum-mechanical wave function of a charged carrier [44] …”
Low power supply operation with leakage power reduction is the prime concern in modern nano-scale CMOS memory devices. In the present scenario, low leakage memory architecture becomes more challenging, as it has 30% of the total chip power consumption. Since, the SRAM cell is low in density and most of memory processing data remain stable during the data holding operation, the stored memory data are more affected by the leakage phenomena in the circuit while the device parameters are scaled down. In this survey, origins of leakage currents in a short-channel device and various leakage control techniques for ultra-low power SRAM design are discussed. A classification of these approaches made based on their key design and functions, such as biasing technique, power gating and multi-threshold techniques. Based on our survey, we summarize the merits and demerits and challenges of these techniques. This comprehensive study will be helpful to extend the further research for future implementations.
