Alphabet jumps the most since October on Willow quantum chip breakthrough

Alphabet Inc. shares (GOOG) surged 6.3% Tuesday, marking the biggest jump since October, following the announcement of a significant quantum computing milestone.

The Google parent introduced the Willow quantum chip, claiming it could solve problems in just five minutes that would take supercomputers 10 septillion years.

This breakthrough underscores Google's decade-long commitment to quantum computing, a journey initiated by CEO Sundar Pichai in 2012 with the establishment of Google Quantum AI.

The announcement propelled Alphabet shares to their highest level since July, building on a 25% rally from a September low. By 11:10 am, GMT+5, the stock had given up some of the gains and was trading higher by 3.8%.

Why is the Willow quantum chip a breakthrough?

While introducing Willow on X, Pichai described it as a breakthrough "that can reduce errors exponentially as we scale up using more qubits, cracking a 30-year challenge in the field".

Willow achieved a groundbreaking milestone, completing a standard benchmark computation in less than five minutes—a task that would take today's fastest supercomputers an astonishing 10 septillion years (10²⁵), a timespan far surpassing the age of the universe.

The program aims to harness the principles of quantum mechanics to drive scientific progress and tackle global challenges.

The announcement elicited a succinct but striking response from Tesla CEO Elon Musk, who shared his amazement with a single word, “wow,” on the social media platform X, emphasizing the magnitude of Google's achievement in the quantum realm.

While Alphabet has not disclosed immediate applications for this breakthrough, analysts have praised it as a pivotal step toward the commercialization of quantum computing.

Colin Sebastian, an analyst at Baird, noted that while widespread adoption of quantum technology is still years away, Willow highlights Alphabet's technological leadership.

Bloomberg Intelligence added that quantum advancements could enhance AI training and inferencing while solidifying Alphabet's chip advantage over other tech giants.

Small quantum stocks ride the wave

The ripple effects of Alphabet’s announcement extended to other quantum-related stocks.

Rigetti Computing soared 29%, while D-Wave Quantum and IonQ gained 6.7% and 5.4%, respectively, in Tuesday’s trading.

Rigetti has experienced a remarkable 600% surge since September, demonstrating the growing investor interest in quantum technology.

Options traders also showed heightened interest in Alphabet, with over 400,000 call options traded by mid-morning, nearly five times the volume of put options.

This spike underscores optimism about Alphabet's potential to leverage quantum computing innovations for long-term growth.

Challenges and opportunities ahead

Despite the enthusiasm, Alphabet faces hurdles, especially including antitrust lawsuits.

Additionally, the potential US ban on TikTok in 2025 could offer limited upside for Alphabet’s YouTube platform.

Analysts estimate that every 10% of TikTok’s reallocated user engagement could add $921 million in YouTube revenue, though profitability gains would be modest due to lower margins.

As Alphabet approaches the year-end, its stock has gained about 32%, narrowly outperforming S&P 500 which has grown by close to 28% during the same period.

However, it continues to lag behind most "Magnificent Seven" tech giants barring Microsoft and Apple, signalling that while quantum breakthroughs are promising, broader challenges still loom.
