Heteroepitaxial Growth of c-BN (111) Films
Cubic BN (c-BN) is a widegap semiconductor with excellent
material properties. For c-BN, the Baliga figure of merit,indicating the expected performance limit for power switching
devices, is larger than those of SiC and GaN. The thin-film
growth of c-BN is difficult although we have successfully
achieved the heteroepitaxial growth of c-BN (111) films on

MBE method. We revealed that the c-BN (111) surface has
nitrogen polarity, which indicates that the B-C bonds are
preferentially formed at the c-BN/diamond heterointerface. An
understanding of the atomic arrangements of the c-BN film andthe heterointerface is important for improving the crystal qualityof c-BN films since this will enable c-BN films to be applied tohigh-efficiency and high-power transistors.

Etching-free Transfer Technique forGraphene Nanoribbon
Among graphene-related materials, graphene nanoribbons(GNRs), whose widths are in the nanometer range, are potential
candidates for semiconductor device applications as they
exhibit electronic bandgaps unlike graphene itself. We havedeveloped a way to mechanically delaminate well-aligned
GNRs from a Au(788) surface by intercalating self-assembled
monolayers (SAMs) into a GNR/Au interface, and thentransferring them to an insulating substrate. Unlike previous
methods, this approach does not require the etching of Au, and
the GNR devices can be fabricated repeatedly by reusing theAu substrate.

Composite Polymer for the Artificial
Assembly of Tissues

Proof-of-concept Experiments Using
Functional Material "hitoe"

We dev el oped a m et h o d fo r re c o n s tru c tin g tin y b io lo g ic a ltissues by incorporating cells into 3D structures that are
entirely composed of highly biocompatible polymer. This method
utilizes soft thin films that are self-assembled into arbitrary
3D shapes, which allows for the encapsulation and long-term
culture of cells. With this 3D structure, the encapsulated cells
are successfully reconstructed into biological tissues suchas cardiac muscle and nerves. We expect this technique tobe used in such applications as flexible substrates for cell
cultures and implantable elements that fit to the surface shapeof biological tissues.

We carried out various proof-of-concept experiments utilizing
the wearable bioelectrode "hitoe", which we jointly developedwith Toray. While promoting open innovation, we are expanding
the use of "hitoe" in experiments including (1) the long-term
activity monitoring of patients undergoing rehabilitation inc o l l a b o r a t i o n w i t h F u j i t a H e a l t h U n i v e r s i t y , (2 ) h e a r t r a t emeasurement and condition monitoring of babies in airplanes inthe "Flying without crying for babies" project being undertaken

Power Generation with Maxwell's Demon
We succeeded in generating an electrical current and powerby performing the Maxwell’s demon operation with nanometerscale silicon transistors. Since Maxwell’s demon is related to
the lower bound of energy consumption in electrical devices
and power generation efficiency in small heat engines, such as
biomolecules, we anticipate that this achievement will help tocreate small, energy-efficient electrical devices.

Error Detection under the Effect of Energy

Magnetic field sensing with a qubit has been studied bymany researchers because of its high sensitivity. Recently,
quantum error correction to suppress noise has been discussed
to improve sensitivity. We have theoretically estimated theperformance of quantum error correction under the effect of
the energy relaxation. We have showed that while a typicalquantum error correction strategy proposed for quantum sensors
does not actually improve sensitivity, this can be achieved withan alternative strategy called quantum error detection.

Frequency-division-multiplexing logic gates are implemented
using an electromechanical phonon waveguide. This device
has broad phonon bands that enable multiple input and output
signal waves to be processed in parallel. Moreover, by adjusting
the number, frequency and phase of the control signal waves
we can selectively execute fundamental logic gates such as
AND, OR and XOR. The results show the availability of phonon
vibrations in a signal processing application.

Gate Control of Spin Orbit Interaction in a
Nanowire FET
We have developed a gate-all-around InAs nanowire MOSFET
using a thin high-k gate insulator, which enables the electricfield to be applied uniformly and strongly around an InAs
channel. As a result, the Rashba spin orbit interaction, which
is proportional to the electric field, was effectively controlled
by the gate voltage. The gate controllability obtained for our
device is 10 times higher than that obtained for the MOSFETs
and Schottky FETs that have been studied as promising
candidates for spin FETs. Our results will pave the way torealizing low power consumption spin FETs.

Quantum State Tomography for a Highdimensional Time-bin StateElectron Spin Manipulation by Drift-induced
Spin-orbit Interaction

A high-dimensional quantum state has been intensively
investigated for advanced quantum information processing.
Quantum state tomography (QST) is a key method forevaluating the quality of a quantum state. However, as thedimension of a quantum state under test increases, themeasurement procedure becomes more complex. We haverealized a simpler QST method for a high-dimensional time-bin
state of a photon using cascaded optical interferometers. With
the proposed scheme, we observed a four-dimensional quantum
entanglement with a fidelity of 95 % with only 16 measurement
settings.

We observe (with a highly-sensitive spin-resolved microscope)that the precession period of drifting electron spins incompound semiconductors depends on drift velocity. Thisphenomenon is due to a drift-induced effective magnetic field.
Our finding will be beneficial for a further understanding of SOIrelated phenomena as well as for spintronics applications using
spin transport with electric fields in semiconductors.

Nonlinear systems are well known to exhibit many interestingand important phenomena that have profoundly changed

novel quantum systems through hybridization has allowed us
to explore such nonlinear effects in systems with no natural
analog. We investigated amplitude bistability in a hybrid
system composed of a superconducting resonator coupled toan ensemble of NV centers and demonstrated a critical slowing
down of 1000+ seconds in the cavity population. This shows
the potential for realizing future quantum technologies basedon nonlinear phenomena.

Ultralow-energy Optical Modulator Based on Photonic Crystal
We fabricated a compact optical modulator by embedding electroabsorptive InGaAsP material in a photonic-crystal waveguide,and demonstrated optical modulation with a low signal voltageof <1 V and a high bit rate of up to 56 Gbits/s. Since almost nobias voltage is required, the photocurrent dissipation energy,
which has been a significant bottleneck for the previous electroabsorptive modulator, was greatly reduced. In addition, the low
capacitance of only about 10 fF suppresses the charging energy
when driving the device. These are the keys to reducing theenergy consumption to only 2 fJ per bit, which is promising fordense electro-optic conversion and consequent high-performance
photonic information processing on a chip.

The twentieth century saw the discovery of quantum mechanics, a setof principles that explains the nature of matter and light at the atomic
level. These counter-intuitive principles have not only dramaticallychanged our understanding of the reality of our physical world but
also enabled a technological revolution. They are responsible forthe digital age in which we live. Naturally arising questions are whatfurther can we learn from these principles and what technologicaladvances could be enabled. The newly formed Center for Theoretical
Quantum Physics established in July 2017 brings together diverse

Aggregated Quantum Repeaters for the
Quantum Internet
The quantum internet holds promise for accomplishing quantum
communication, such as quantum teleportation and cryptography,
freely between arbitrary clients all over the globe, as well as
the simulation of quantum many-body systems. We propose auniversal quantum internet protocol that works over any quantum
network irrespective of its quantum channels and topology. This
protocol is based on the idea of simply running quantum repeater
protocols in parallel between communicators. Nonetheless, theprotocol achieves the quantum/private capacity of any opticalfiber network, namely the quantum theoretical limit to theperformance.
