We study the model of a mass enhancement in the supersymmetric quantum mechanics. This model is so simple that it may be implemented as a quantum simulation of the mass enhancement taking place when supersymmetry (SUSY) is spontaneously broken. It is evolved from a prototype based on the quantum Rabi model. Here, our quantum simulation means the realization of the target quantum phenomenon as a physical entity with some quantum-information devices. The original prototype is given as a mathematical model, and has the transition from the N=2 SUSY to its spontaneous breaking, though it has no mass enhancement. It is recently reported that the transition is observed for this prototype in a trapped-ion experiment with devising a method experimentally to realize the transition. The model proposed in this paper describes how the mass enhancement takes place in the fermionic states by the excitation of the 1-mode light boson in the SUSY breaking. In this model, the bosonic and fermionic states are graded by qubits. Although our model’s interaction does not have the Higgs potential, the mass enhancement in the fermionic states is caused by the radiative enhancement with the help of the X-gate’s swap between the fermionic and bosonic states.

We have proposed a concealing-restoring system (CRS), which is for the security of the digital data on the physical layer of the open-systems-interconnection reference model. Primarily, the main body (MB) of CRS shoulders the concealing and restoring of analog signals which should be transformed into the digital data on the physical layer. MB conceals an original, analog signal by the random-noise disturbance, and makes the concealed signals. MB also restores the analog signal from the concealed signals using the proper noise elimination based on the stochastic filtering theory. In this paper, thus, we apply the CRS to analog signals, and briefly report its performance of the restoration. Going through the results of those experiments, we give some mathematical conjectures.

We handle all the self-adjoint extensions of the minimal Schrödinger operator for the nonrelativistic electron living in the one-dimensional configuration space with a junction. We are interested in every boundary condition corresponding to the individual self-adjoint extension. Thus, we clarify all the types of those boundary conditions of the wave functions of the nonrelativistic electron. We find concrete tunnel-junction formulae for the nonrelativistic electron passing through the junction, which reveals the phase factor caused by the tunneling through the junction. Using this tunnel-junction formula, we propose a mathematical possibility of a tunnel-junction device for qubit.

We show a mathematical relation between the potential of the rotating wave approximation and an estimation of the fluctuation in Mori′s theory of generalized Brownian motion. We use this relation to prove that, when an autocorrelation function R_A(t), t ∈ R concerning the Bogoliubov scalar product is given for a certain quantum observable A in an equilibrium quantum system in finite volume, we can obtain a Hamiltonian H_RWA by making the rotating wave approximation from R_A(t) such that we reconstruct the autocorrelation function R_A(t) in the system governed by H_RWA.

　More details

我々が研究している秘匿化・復号システムは，OSI参照モデルの物理層データをデータリンク層から秘匿化し，それを復号するものです．基本的なアイディアは物理層のバイナリ・データと電気信号の変換において，電気信号をランダムなノイズで攪乱することでデータを秘匿化し，この秘匿化した信号に対してノイズ除去により復号を行います．従って，我々の秘匿化・復号システムの核になるものは確率フィルタリングの理論になります．この応用として，通常，OSI参照モデルの上の層で行われる画像データや文章データの暗号化とは違った，OSI参照モデルの下の層のデータの秘匿化や復号を狙っています．ここでは，文章に対する応用を例示しますが，画像に関しては論文を参照してください．今後，ファームウェア攻撃，サイド・チャンネル攻撃，さらにはIoTにおけるデバイスへの攻撃に対するセキュリティへと応用を行う予定でいます．特に，量子センサを持った計測装置が扱う究極の個人情報のセンシング・デバイス内でのデータの秘匿化や，量子コンピュータのアーキテクチャ・レベルでのデータの秘匿化に興味を持っています．
