Extracting Current Waveforms of Appliances from Mixed Current Waveform of Their Current Waveforms and Unidentified Current Waveforms

F. Ishiyama, H. Inoue, and Y. Suzuki

Proc. of 2016 IEEE 12th International Colloquium on Signal Processing & its Applications (CSPA2016), pp. 16–21, Melaka, Malaysia, March 2016.

We propose a method of extracting current waveforms of appliances from the current waveform, which is a mixture of their current waveforms and unidentified current waveforms. The purpose of the method is to monitor the load of individual appliances by analyzing the current waveform on a power distribution board. Since the mixed current waveform contains unidentified current waveforms, a special method is required. Therefore, we propose to apply our method, called the “inscribed fitting method” with an asymmetric evaluation function, for the extraction. We apply our method to the mixed current waveforms of appliances, showing that we can extract the current waveforms of appliances from the mixed current waveforms which contain unidentified current waveforms.

Ancilla-driven Instantaneous Quantum Polynomial Time Circuit for Quantum Supremacy

Y. Takeuchi and Y. Takahashi

arXiv:1611.00510 [quant-ph], November 2016.

Instantaneous quantum polynomial time (IQP) is a model of (probably) non-universal quantum computation. Since it has been proven that IQP circuits are unlikely to be simulated classically up to a multiplicative error and an error in l1 norm, IQP is considered one of the promising classes that demonstrate quantum supremacy. Although IQP circuits can be realized more easily than a universal quantum computer, demonstrating quantum supremacy is still difficult. It is therefore desired to find subclasses of IQP that are easy to implement. In this paper, by imposing some restrictions on IQP, we propose ancilla-driven IQP (ADIQP) as the subclass of commuting quantum computation suitable for many experimental settings. We show that even though ADIQP circuits are strictly weaker than IQP circuits in a sense, they are also hard to simulate classically up to a multiplicative error and an error in l1 norm. Moreover, the properties of ADIQP make it easy to investigate the verifiability of ADIQP circuits and the difficulties in realizing ADIQP circuits.
