Information processing apparatus and apparatus for evaluating whether information processing method is possible

An information processing apparatus for evaluating the function of a device or an apparatus concerning each of individual microscopic massive particles comprising:

• an analyzer using at least a statistical wave function defined as an evaluation function for evaluating the function of said device or apparatus concerning said microscopic particles;
• said analyzer comprising:
• N number of devices or N number of two-level particles capable of being in either of two different states concerning microscopic particles, wherein the state of said N number of devices or said N number of two-level particles after the time t elapses is represented by ψ(t)=(2−t/τ)1/2ψ1(t)+(1-2−t/τ)1/2ψ2(t) based on a premise that in an initial condition all of said N number of devices or said N number of two-level particles are in an excited state at time t=0, where τ denotes the half-life in the excited state, ψ1(t) denotes a statistical wave function representing the excited state, and ψ2(t) denotes a statistical wave function representing a ground state;
• an outputter for outputting evaluation result obtained by said analyzer, wherein said statistical wave function represents at least one state of an ensemble of said microscopic particles;
• said information processing apparatus further comprising:
• an inputter for inputting at least a half-life τ concerning said N number of devices or said N number of two-level particles and a time t or a ratio t/τ of the time t to the half-life τ;
• a memory for storing at least one of the two formulas (2−t/τ) and (1-2−t/τ) obtained by carrying out the square of each of two individual coefficients included in the expression of said ψ(t) and at least the half-life τ of said N number of devices or said N number of two-level particles and the time t or the ratio t/τ of the time t to the half-life τ input by said inputer;
• and
• a calculator for calculating at least one of the values of (2−t/τ) and (1-2−t/τ) or, when the number N of said devices or said two-level particles has been input, at least one of the number of said devices or said two-level particles 2−t/τ N in the excited state and the number of the devices or two-level particles (1-2−t/τ) N in the ground state, based on at least one of said stored formulas (2−t/τ) and (1-2−t/τ) and at least said stored half-life τ concerning said N number of devices or said N number of two-level particles and the time t or said stored ratio t/τ of the time t to the half-life τ.
