Source Text: The Quantum Leap

The advent of quantum computing promises to usher in an era of unprecedented processing power. Unlike classical computers, which rely on binary bits, quantum computers utilise qubits, allowing them to perform complex calculations at speeds previously thought impossible. This could revolutionise fields such as cryptography, material science, and drug discovery.

However, this technological leap is not without its pitfalls. The stability of qubits is notoriously difficult to maintain, a phenomenon known as decoherence. Furthermore, the sheer power of quantum decryption could render current cybersecurity measures obsolete, creating a global security crisis. While the potential benefits are immense, the transition period may be fraught with technical and ethical challenges. We must decide whether the pursuit of such power justifies the inherent risks to our digital infrastructure.

Writing Task

Instrucciones: Basándote en el texto anterior, escribe un ensayo de opinión (opinion essay) de entre 180 y 220 palabras. Debes evaluar si los beneficios de la computación cuántica compensan los riesgos de seguridad y éticos. Utiliza un registro formal y emplea al menos dos estructuras de concesión (por ejemplo: 'While...', 'Admittedly...') para contrastar tus argumentos.

Speaking checkpoint

Answer the following prompts. Aim for extended responses of 1-2 minutes each.

1. Compare: Compare the impact of the industrial revolution with the potential impact of the AI revolution.
2. Speculate: How might the world change if we successfully achieve human immortality through biotechnology?
3. Evaluate: Evaluate the statement: "Technological progress is always beneficial for humanity."
4. Justify: Justify why governments should or should not regulate the development of quantum technologies.
5. Contrast: Contrast the way classical physics explains the world with the way quantum physics does so.
6. Hypothesise: If you could use a time machine (a theoretical possibility in some physics models), would you use it? Why or why not?
