Physically unclonable function using initial waveform of ring oscillators on 65 nm CMOS technology
Tetsufumi Tanamoto, Satoshi Takaya, Nobuaki Sakamoto +5
A silicon physically unclonable function (PUF) using ring oscillators (ROs) has the advantage of easy application in both an application specific integrated circuit (ASIC) and a fi…
High-Speed Magnetoresistive Random-Access Memory Random Number Generator Using Error-Correcting Code
Tetsufumi Tanamoto, Naoharu Shimomura, Sumio Ikegawa +3
A high-speed random number generator (RNG) circuit based on magnetoresistive random-access memory (MRAM) using an error-correcting code (ECC) post processing circuit is presented.…
Physically Unclonable Function using Initial Waveform of Ring Oscillators
Tetsufumi Tanamoto, Shinich Yasuda, Satoshi Takaya +1
A silicon physically unclonable function (PUF) is considered to be one of the key security system solutions for local devices in an era in which the internet is pervasive. Among ma…
The Effect of Side Traps on Ballistic Transistor in Kondo Regime
Tetsufumi Tanamoto, Ken Uchida, Shinobu Fujita
The effect of side-traps on conductance is calculated in the range of slave-boson mean field theory, especially when there are electrodes on both sides of the conductor. This corre…
Producing cluster states in charge qubits and flux qubits
Tetsufumi Tanamoto, Yu-xi Liu, Shinobu Fujita +2
We propose a method to efficiently generate cluster states in charge qubits, both semiconducting and superconducting, as well as flux qubits. We show that highly-entangled cluster…
The Effect of Local Structure and Non-uniformity on Decoherence-Free States of Charge Qubits
Tetsufumi Tanamoto, Shinobu Fujita
We analyze robustness of decoherence-free (DF) subspace in charge qubits when there are a local structure and non-uniformity that violate collective decoherence measurement conditi…
