2. Quantum Computing Explained
Quantum Computing Explained
To understand the potential of quantum computing in revolutionizing artificial intelligence and wealth creation, it's important to grasp the fundamental principles that set it apart from classical computing.
The Classical vs. Quantum Difference
Classical computers, like the ones in our everyday devices, store and process information using bits. Each bit represents either a 0 or a 1. Quantum computers, on the other hand, use qubits. Qubits leverage the principles of quantum mechanics to exist in multiple states simultaneously, enabling them to tackle extraordinarily complex problems.
Why This Matters
This difference is crucial because it allows quantum computers to solve problems that are practically impossible for even the most powerful classical supercomputers. The capacity to accurately model the laws of nature, simulate molecular interactions, and optimize complex systems opens doors to advancements in medicine, materials science, finance, and artificial intelligence.
Key Concepts
Superposition: Unlike classical bits that can only be 0 or 1, a qubit can exist in a superposition of both states simultaneously. This means a quantum computer can explore many possibilities at once, vastly increasing its computational power.
Entanglement: Entanglement links two or more qubits together in such a way that they become interconnected. The state of one qubit instantly influences the state of the others, regardless of the distance separating them. This allows for complex correlations and parallel computations.
Interference: Quantum interference allows for the manipulation of qubit states to either amplify desired outcomes or cancel out unwanted ones. By carefully controlling interference, quantum computers can find the optimal solutions to complex problems

4. The Biggest Breakthroughs in Quantum Computing
Quantum computing has seen significant breakthroughs recently, especially in the areas of qubit technology and error correction. Some of the biggest breakthroughs include:
1. Microsoft's Majorana 1 Chip:
This quantum chip is built on a topological core using topoconductors, a new class of materials. This design enables stable and scalable qubits. The Majorana 1 chip uses Majorana particles for computing, which are distinct from using electrons in regular chips. This allows for the potential to store over a million qubits on a small chip. Microsoft's approach involved creating a new state of matter, the topological phase, to achieve this.
What is a qubit? A qubit is the fundamental unit of information in a quantum computer, analogous to a bit in a classical computer However, unlike a classical bit, which can only be in a state of 0 or 1, a qubit can exist in multiple states simultaneously. This property enables quantum computers to tackle extraordinarily complex problems.2. Google's Willow Chip:
Willow is Google Quantum AI's latest superconducting quantum computing chip. It has achieved a significant increase in quantum coherence times, from 20 microseconds in Sycamore to 100 microseconds in Willow. Willow has demonstrated logical qubits operating below the critical quantum error correction threshold. Willow has a large number of qubits with high connectivity and can run diverse applications. It also employs tunable qubits and couplers for fast gates, low error rates, and reconfigurability.
3. Quantum Error Correction:
Error correction is crucial due to the fragility of qubits. Environmental noise can easily disrupt qubits, leading to calculation errors, so quantum error correction methods are needed to make qubits reliable. Google's team has demonstrated surface code memories operating below the threshold on Willow processors. Their research showed a logical error rate of their quantum memory was suppressed by a factor of 2.14 when increasing the code distance from 5 to 7, culminating in a 101-qubit distance-7 code with 0.143% error per cycle. A key milestone to watch for is the demonstration of quantum error correction with topological qubits.
4. Topological Qubits:
Microsoft is using topological qubits, which differ from traditional approaches. Topological qubits store information across a quantum system, making them more resistant to errors. Majorana particles, which are key to topological qubits, offer natural protection against interference due to their exotic quantum states.
These breakthroughs signify substantial progress toward building practical and scalable quantum computers, with potential applications spanning drug discovery, materials science, financial modeling, and more.

Willow has achieved a significant increase in quantum coherence times, from 20 microseconds in Sycamore to 100 microseconds in Willow.
Willow has demonstrated logical qubits operating below the critical quantum error correction threshold. This means errors are exponentially suppressed in logical qubits as physical qubits are added and scaled.
Willow's logical qubit lifetimes are longer than the lifetimes of the physical qubits that compose them, so that as quantum chips become larger and more complex, quantum error correction can improve their accuracy.
In a comparison with one of the world's most powerful supercomputers using the random circuit sampling benchmark, Willow completed a calculation in under 5 minutes that would take the supercomputer 10 to the 25 years.
Willow hits a sweet spot across a full list of performance metrics. It combines a large number of qubits with high connectivity and the ability to run diverse applications. It also achieves low mean error rates across all operations with multiple native two qubit gates.
Willow employs tunable qubits and couplers for fast gates, low error rates, and reconfigurability.
Google Quantum AI and collaborators have demonstrated surface code memories operating below the threshold on Willow processors. Their research showed a logical error rate of their quantum memory was suppressed by a factor of 2.14 when increasing the code distance from 5 to 7, culminating in a 101-qubit distance-7 code with 0.143% error per cycle.
A distance-5 surface code was implemented on a 72-qubit processor, operating with an integrated real-time decoder. Subsequently, a distance-7 surface code was realized using a 105-qubit processor.
The processors demonstrated a value greater than 2 up to distance 5 and 7, respectively. The distance-5 and distance-7 quantum memories are beyond break-even, with distance-7 preserving quantum information for more than twice as long as its best constituent physical qubit.
