Macroscopic Quantum Tunneling in a Bi2Sr2CaCu2O8+δSingle Crystalline Whisker

“…[12][13][14] Single crystalline whiskers of BSCCO 15) have been regarded as a favorable material to realize intrinsic phase qubits 16) or intrinsic flux qubits, 17) because their thin and long shape is suitable to fabricate small IJJ stacks. 15,18,19) In addition, we can easily grow the whiskers without complicated procedures and expensive equipments such as a floating zone furnace. 15) Nevertheless no experimental demonstration of MQT has been done in BSCCO whisker single crystals.…”
