Outline

一、使用 google drive

二、figure 與 axes

三、量子位元符號

四、代碼 2.1

Fig. 2.1. Classical bit and quantum bit.

一、使用 google drive

「

from google.colab import drive

drive.mount('/content/drive/')

!ls '/content/drive/My Drive/'

」[1]。

-----

二、figure 與 axes

「fig, ax = plt.subplots()

is more concise than this:

fig = plt.figure()

ax = fig.add_subplot(111)」[3]。

三、量子位元符號

四、代碼 2.1

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

# Program 2.1：cbit(classical bit) and qubit(quantum bit) import matplotlib.pyplot as plt fig = plt.figure(figsize=(16, 16)) ax = fig.add_subplot(111) ax.text(0.05, 0.6, "Classical Bit:", fontsize=60) ax.text(0.05, 0.4, "Quantum Bit:", fontsize=60, color="red") ax.text(0.65, 0.6, "0, 1", fontsize=60) ax.text(0.65, 0.4, r"$\vert0\rangle,\vert1\rangle$", fontsize=60, color="red") # Remove axis planes, ticks and labels ax.set_axis_off() # plt.savefig('/content/drive/My Drive/pqc/0002_001.png') plt.show()
