    Abstract: There is provided a method of detecting a microscopic body stored in a plurality of receptacles formed separately from each other. The method, which is provided as a technique for enclosing a to-be-detected substance such as nucleic acid, protein, virus, and cell by means of a simple operation in droplets of an extremely small volume and enabling highly sensitive detection, includes the steps of (1) introducing a solvent into a space between a lower layer part in which the receptacles are formed and an upper layer part facing a surface of the lower layer part in which surface the receptacles are formed, wherein the solvent contains the microscopic body; (2) introducing gas into the space to form a droplet of the solvent in the receptacles, wherein the droplet contains the microscopic body; and (3) detecting the microscopic body present in the droplet optically, electrically, and/or magnetically.

    Abstract: A microwave photon control device includes a first qubit and a second qubit that are connected in parallel to a waveguide through which microwave photons propagate, and a direct coupling between the first qubit and the second qubit. An interval between the first qubit and the second qubit is (¼+n/2) times as long as a wavelength of microwave photons (where n is an integer equal to or larger than 0). A quantum entangled state is formed between the first qubit and the second qubit. The direct coupling cancels out a coupling via the waveguide between the first qubit and the second qubit. By a relaxation rate of the first qubit and the second qubit, and a phase of the quantum entangled state being controlled, the microwave photon control device operates while switching between a first operation mode, a second operation mode, and a third operation mode.

    Abstract: A quantum computation controller according to one embodiment has a control signal generator, an observation unit that receives an observation signal indicating the state of each qubit and a qubit module. The qubit module has a qubit substrate on which a plurality of qubits are arranged, a control circuit, an observation circuit, and a signal processing circuit. The qubits are grouped into a plurality of groups. The control signal generator generates a control signal for performing a first operation, a control signal for performing a second operation and an instruction signal. The control circuit splits the control signal into groups and controls the sending of the control signal. The observation circuit observes the state of each qubit on which the first operation or the second operation has been performed. The signal processing circuit sends the observation signal of each qubit to the observation circuit.

    Abstract: A quantum entanglement generator comprises two superconducting qubit elements, each having three electrodes, where n is an integer greater than or equal to, a coupling resonator disposed between adjacent superconducting qubit elements and a waveguide capacitively coupled to each of the superconducting qubit elements and to each other. The coupling resonator generates quantum entanglement between the adjacent superconducting qubit elements by acting a two-qubit gate between the adjacent superconducting qubit elements. The superconducting qubit elements emit the quantum entanglement as a propagating microwave photon into the waveguide, thereby generating a two-dimensional cluster state.
