Optical dynamic nuclear polarization of C spins in diamond at a low field with multi-tone microwave irradiation
Vladimir Vladimirovish Kavtanyuk, Hyun Joon Lee, Sangwon Oh +2
Most of dynamic nuclear polarization (DNP) has been requiring helium cryogenics and strong magnetic fields for a high degree of polarization. In this work, we instead demonstrate a…
Two-photon interferences of weak coherent lights
Heonoh Kim, Osung Kwon, Han Seb Moon
Multiphoton interference is an important phenomenon in modern quantum mechanics and experimental quantum optics, and it is fundamental for the development of quantum information sc…
Polynomial T-depth Quantum Solvability of Noisy Binary Linear Problem: From Quantum-Sample Preparation to Main Computation
Wooyeong Song, Youngrong Lim, Kabgyun Jeong +4
The noisy binary linear problem (NBLP) is known as a computationally hard problem, and therefore, it offers primitives for post-quantum cryptography. An efficient quantum NBLP algo…
Time-resolved two-photon interference of weak coherent pulses
Heonoh Kim, Osung Kwon, Han Seb Moon
The observation of the Hong-Ou-Mandel (HOM)-type two-photon interference (TPI) has played an important role in the development of photonic quantum technologies. The time-resolved c…
Fundamental limits on concentrating and preserving tensorized quantum resources
Jaehak Lee, Kyunghyun Baek, Jiyong Park +2
Quantum technology offers great advantages in many applications by exploiting quantum resources like nonclassicality, coherence, and entanglement. In practice, an environmental noi…
