Parameter estimation of qubit states with unknown phase parameter
Jun Suzuki
We discuss a problem of parameter estimation for quantum two-level system, qubit system, in presence of unknown phase parameter. We analyze trade-off relations for mean-square erro…
Highly efficient entanglement swapping and teleportation at telecom wavelength
Rui-Bo Jin, Masahiro Takeoka, Utako Takagi +2
Entanglement swapping at telecom wavelengths is at the heart of quantum networking in optical fiber infrastructures. Although entanglement swapping has been demonstrated experiment…
Efficient generation of twin photons at telecom wavelengths with 10 GHz repetition-rate tunable comb laser
Rui-Bo Jin, Ryosuke Shimizu, Isao Morohashi +10
Efficient generation and detection of indistinguishable twin photons are at the core of quantum information and communications technology (Q-ICT). These photons are conventionally…
Strong converse exponent for classical-quantum channel coding
Milan Mosonyi, Tomohiro Ogawa
We determine the exact strong converse exponent of classical-quantum channel coding, for every rate above the Holevo capacity. Our form of the exponent is an exact analogue of Arim…
Two approaches to obtain the strong converse exponent of quantum hypothesis testing for general sequences of quantum states
Milán Mosonyi, Tomohiro Ogawa
We present two general approaches to obtain the strong converse rate of quantum hypothesis testing for correlated quantum states. One approach requires that the states satisfy a ce…
