His primary areas of investigation include Optics, Photon, Quantum key distribution, Ising model and Quantum optics. Many of his research projects under Optics are closely connected to Waveguide with Waveguide, tying the diverse disciplines of science together. His Photon research incorporates themes from Polarization, Four-wave mixing, Optical fiber, Lithium niobate and Amplified spontaneous emission.
His studies deal with areas such as Key generation, Quantum cryptography and Quantum network as well as Quantum key distribution. The study incorporates disciplines such as Complex system and Spins in addition to Ising model. His studies examine the connections between Quantum optics and genetics, as well as such issues in Dispersion-shifted fiber, with regards to Ballistic photon, Photon counting and Noise.
Hiroki Takesue mainly investigates Optics, Photon, Optoelectronics, Quantum entanglement and Quantum key distribution. Optics is closely attributed to Spontaneous parametric down-conversion in his study. Hiroki Takesue has researched Photon in several fields, including Four-wave mixing, Nonlinear optics, Dispersion-shifted fiber and Interference.
In his research on the topic of Optoelectronics, Chip is strongly related with Polarization. When carried out as part of a general Quantum entanglement research project, his work on Photon entanglement and Quantum information science is frequently linked to work in Bin, therefore connecting diverse disciplines of study. His Quantum key distribution study combines topics from a wide range of disciplines, such as Quantum channel, Avalanche photodiode, Detector, Quantum cryptography and Differential phase.
His main research concerns Ising model, Degenerate energy levels, Quantum, Statistical physics and Topology. His studies in Degenerate energy levels integrate themes in fields like Optical parametric oscillator, Condensed matter physics, Spin-½ and Optics. Hiroki Takesue works on Optics which deals in particular with Optical amplifier.
Hiroki Takesue interconnects Quantum channel, Oscillation and Phase modulation in the investigation of issues within Topology. His Quantum channel research incorporates elements of Quantum key distribution, Photon and Qubit. His Photon research is multidisciplinary, incorporating elements of Photonics and Silicon photonics.
His primary scientific interests are in Ising model, Statistical physics, Quantum, Degenerate energy levels and Optical parametric oscillator. His biological study spans a wide range of topics, including Construct and Quantum limit. In his research, Spin-½ and Statistical mechanics is intimately related to Scale, which falls under the overarching field of Statistical physics.
As a member of one scientific family, Hiroki Takesue mostly works in the field of Quantum, focusing on Exponential function and, on occasion, Superconductivity. His Optical parametric oscillator study incorporates themes from Discrete mathematics, Spins and Langevin dynamics. His study looks at the relationship between Spins and fields such as Quantum mechanics, as well as how they intersect with chemical problems.
